Car Key Replacement Services Across the Portsmouth Area
Mobile Replacement Car Keys at Your Location
A mobile auto locksmith can cut, programme, and pair a replacement car key at your location across the Portsmouth area, without a dealership visit or recovery truck.
Losing a car key anywhere in Portsmouth creates an immediate problem. Portsmouth Car Keys operates a fully equipped mobile unit carrying programming hardware and blank key stock, allowing us to produce working replacement keys on the spot, from a Ford driver near Gunwharf Quays to a Volkswagen owner in Southsea. Modern keys carry a transponder chip that must communicate with the vehicle’s immobiliser before the engine will start, so cutting the blade is only part of the job. We handle the full programming process too.
- Same-day mobile service across Portsmouth
- All makes and models covered
- No dealership delays or towing required
- Fully equipped vans for on-the-spot fixes

Roadside Vehicle Locksmith Assistance
Portsmouth Car Keys provides roadside car locksmith assistance across Portsmouth for drivers locked out of their vehicles or dealing with a key failure at any location.
A driver locked out near the Portsmouth Historic Dockyard or along the M275 approach into the city doesn’t need to wait hours for help. Our mobile response is built around speed of attendance, and we carry specialist non-destructive entry tools that allow us to regain access to most vehicles without causing damage. Once the door is open, we assess whether the key itself needs attention. A snapped remote flip key or a worn blade can often be addressed in the same visit, avoiding a second callout later.
Lost Key Replacement
Lost every key to your car in Portsmouth? No tow truck, no dealership wait.
All-keys-lost is our most common Portsmouth call-out. Our engineer arrives in an unmarked van, connects to your vehicle's diagnostic port, reads the immobiliser data, and cuts a fresh OEM-grade blade and programs a new remote on the spot.
- Fresh OEM blade cut on-site
- Old lost keys wiped from memory for security
- New remote paired to your immobiliser
- Typical job: 45–90 minutes driveway-side
Spare Car Keys
Avoid the £400+ dealer quote — get a spare cut at home or work.
A spare key is the cheapest insurance policy you'll ever buy. We cut and program a genuine-quality spare to match your existing key exactly, at your home, workplace or even Portsmouth town centre. Takes roughly 30 minutes per key, no appointment required — just call and we'll be over.
- Cut from your existing working key
- Up to 60% cheaper than main dealer
- Fully programmed remote & transponder
- Visit at home, work, or anywhere in PO9
Ignition Lock Repair & Replacement
Key won’t turn or stuck in the ignition in Portsmouth? No recovery needed. We fix it on your driveway.
Ignition problems usually start with wear inside the lock or a damaged key. What feels like a minor issue quickly turns into a non-start or a key that won’t come out. Our engineer comes to you, strips the ignition if needed, repairs the internal components, and gets everything turning smoothly again without replacing parts unnecessarily.
Where a repair isn’t possible, we supply and fit a replacement ignition and match it to your existing key or supply a new one, all completed on-site.
- Ignition stripped, repaired, and rebuilt on-site
- Stiff, worn, or seized ignitions fixed
- Broken or snapped keys safely removed
- Replacement ignitions supplied and fitted if required
Locked Out Vehicle Entry
Locked your keys in the car in Portsmouth? No damage, no stress. We’ll have you back in within minutes.
Lockouts happen to everyone - keys left on the seat, in the boot, or locked inside with the engine running. Our engineer comes straight to you and gains entry using specialist tools that protect your vehicle. No broken glass, no forced locks, just a quick and controlled entry so you can get moving again.
We cover most makes and models, including modern vehicles with deadlocks and keyless systems.
- Non-destructive entry methods used
- Fast response across Portsmouth and surrounding areas
- Access gained without damage to locks or doors
- Key retrieval from boot, cabin, or locked ignition
Professional Car Key Programming Services
Portsmouth Car Keys programmes replacement and spare keys on-site using automotive diagnostic equipment compatible with a wide range of modern vehicle makes and models.
Programming a replacement key involves more than copying a profile. Depending on the make and model, the process may require communicating with the Body Control Module (BCM), the Engine Control Module (ECM), or a dedicated immobiliser box. For Audi and Volkswagen models, key data is typically written through the OBD port, while BMW vehicles often require communication with the CAS or FEM module. We carry the equipment to handle these procedures correctly, meaning the driver receives a key that opens the door and starts the engine.

Common Vehicle Key Problems Drivers Experience
Lost Vehicle Keys While Away From Home
A lost car key in Portsmouth can be replaced on-site by Portsmouth Car Keys, even where no spare key exists, without the need for a dealership or recovery service.
Losing the only set of keys leaves the immobiliser without a recognised transponder, meaning the vehicle will not start regardless of physical access. We attend the location, generate a new key with the correct transponder profile, and pair it to the immobiliser so the vehicle starts normally. It’s a situation that can happen anywhere, returning to a car at Portsmouth Harbour station, finishing a shift near Fratton, or spending an afternoon on the seafront at Southsea.
Keys Locked Inside the Car
Drivers who have locked their keys inside their vehicle in the Portsmouth area can contact Portsmouth Car Keys for fast, non-destructive entry using specialist automotive tools.
Getting the door open without damage is the immediate priority. We use professional wedge and rod tools designed specifically for automotive entry, protecting the weatherstripping, locking mechanisms, and paintwork throughout. A call about keys locked inside a car often comes at the worst possible moment, dropping a child at school near Cosham, finishing shopping at Gunwharf Quays, or preparing to leave for work from Hilsea. Our mobile coverage reaches across the full city and surrounding roads.
Broken Car Keys or Worn Key Blades
A broken or worn car key can be repaired or replaced on-site by Portsmouth Car Keys, including extraction of snapped blade fragments from door locks and ignition barrels.
Key blades wear over time, and eventually the lock no longer reads the profile reliably. A snapped blade inside a door lock or ignition barrel requires extraction before any new key will work. We carry extraction tools designed for automotive locks, and once the fragment is removed, we supply and programme a replacement to match the vehicle. Where a remote flip key has split from its blade, a shell rebuild is sometimes possible before a full replacement becomes necessary.
Faulty Remote Key Fobs
A faulty car key fob may require battery replacement, re-pairing, or a full replacement remote, which Portsmouth Car Keys diagnoses and resolves at your location.
Remote fobs fail for various reasons. A flat battery is the simplest cause, but a fob that won’t respond even with a new cell may have lost its pairing with the receiver module. Some keyless entry systems need re-synchronisation through the OBD port, while smart key systems used in many Mercedes, BMW, and Toyota models can be sensitive to signal interference or internal component failure. We diagnose the fault first and recommend accordingly, which usually saves the driver both time and money.
Dealing with a broken, lost, or faulty key? Portsmouth Car Keys provides mobile car key repair and replacement across Portsmouth and the surrounding area. Call for same-day attendance.
Why a Mobile Auto Locksmith Is the Best Option
Fast Local Response Across the Region
A mobile auto locksmith provides a faster and more cost-effective response than a dealership or recovery service for most car key emergencies across the Portsmouth area.
Dealerships handle key replacements but rarely on the same day, and never at your location. Recovery trucks add transport time before any key work can begin. A mobile locksmith removes both delays, travelling directly to the driver with tools and key stock already onboard. The M27 links Portsmouth to Fareham and Havant, and the A3(M) connects the city northward. Our coverage follows that road network, keeping response times consistent whether the call comes from Portchester or central Portsmouth.
Specialist Automotive Locksmith Equipment
Portsmouth Car Keys uses professional automotive locksmith equipment for vehicle entry, key cutting, and transponder programming, covering a wide range of modern vehicle security systems.
The right equipment makes the difference. Consumer-grade tools cannot interface with the ECU modules required to programme modern transponder keys. Our hardware communicates with each vehicle’s specific architecture, from a Vauxhall BCM to a Citroen or Peugeot BSI module, a Mercedes EIS system, or the dedicated commercial software needed for an Iveco van. That range of tooling is what allows us to cover such a broad spread of makes without referring jobs elsewhere.
Convenient Mobile Service for Drivers
Portsmouth Car Keys attends the driver’s location for all auto locksmith services, covering homes, workplaces, car parks, and roadsides across the Portsmouth area.
There’s a straightforward logic to mobile locksmith services: the car usually can’t move when a key problem occurs. Drivers in Southsea, Eastney, Fratton, or Hilsea don’t need to arrange alternative transport or pay recovery fees. For businesses running fleet vehicles in and around Portsmouth, the same applies. A Ford Transit, Vauxhall Vivaro, or Fiat Ducato with a key fault needs attending promptly, and we carry commercial vehicle key stock as standard.

Vehicle Locksmith Services Available Across the Portsmouth Area
Spare Car Keys Cut and Programmed
Portsmouth Car Keys cuts and programmes spare car keys on-site across Portsmouth, covering transponder keys, remote flip keys, and smart keys for most makes and models.
A spare key produced while the original is still available is both simpler and more affordable than a full replacement after losing the only set. The programming sequence is shorter when the original key acts as an authority for the new spare. We produce spare car keys for Ford, Nissan, Toyota, Kia, Hyundai, Mazda, and Vauxhall models, among others.
Replacement Remote Car Keys
Replacement remote car keys are produced on-site by Portsmouth Car Keys, covering remote flip keys, keyless entry fobs, and smart key systems for most vehicles.
A remote key with a failed transponder prevents the engine from starting, which is more than a minor inconvenience. We replace the full key, cutting the blade and programming both the transponder and remote functions in a single visit. For Porsche and Land Rover models using proximity-based smart key systems, the programming involves the Kessy module and requires dedicated specialist equipment.
Broken Key Extraction
Portsmouth Car Keys carries out broken key extraction from door locks and ignition barrels, removing snapped fragments before supplying and programming a replacement key.
A snapped blade inside an ignition barrel prevents any new key from being used until it’s removed. Our extraction tools are purpose-built for automotive locks, meaning the fragment can usually be removed without drilling or barrel replacement.
Ignition Lock Repairs
Ignition lock repair across the Portsmouth area is carried out by Portsmouth Car Keys for worn, jammed, or damaged barrels, with replacements coded to existing keys where possible.
Ignition faults and key faults can appear similar, but the cause is different. A barrel worn beyond reliable operation may need replacing, and where the vehicle’s architecture allows, we code the new barrel to the existing key rather than requiring a full key change.
Replacement Keys for Most Vehicle Makes
Ford, Nissan and Toyota Vehicles
Portsmouth Car Keys produces replacement keys for Ford, Nissan, and Toyota vehicles, including transponder keys and remote flip keys programmed at the driver’s location.
Ford remains one of the most common makes across the Portsmouth area, and our hardware covers the full range from Fiesta to Transit. Nissan’s Qashqai and Juke use varied transponder systems depending on year, while Toyota’s more recent models often feature smart key entry requiring KESSY-compatible programming equipment.
BMW, Audi and Mercedes Models
Portsmouth Car Keys replaces and programmes keys for BMW, Audi, and Mercedes vehicles using manufacturer-compatible tools, covering smart keys, remote flip keys, and proximity entry systems.
BMW’s CAS and FEM modules require specific communication protocols. Audi’s immobiliser system often sits within the instrument cluster and is accessed accordingly. Mercedes EIS systems require precise synchronisation across multiple control units. We work on all three makes regularly and carry the hardware to do so correctly.
Volkswagen, Hyundai and Kia
Car key replacement for Volkswagen, Hyundai, and Kia vehicles is available from Portsmouth Car Keys, with on-site programming for transponder and remote entry systems.
Volkswagen Group vehicles are programmed through the OBD port using compatible diagnostic software. Hyundai and Kia have extended their use of advanced immobiliser systems across recent models including the Tucson and Sportage. Citroen, Peugeot, and Mazda also fall within our standard programming range across the Portsmouth area.

Vehicle Locksmith Support Near the M27

02392990167
Can a locksmith make a replacement car key?
Yes, a mobile auto locksmith can make a replacement car key at your location in the Portsmouth area, covering key cutting, transponder programming, and remote pairing in a single visit.
For drivers in Portsmouth who have lost their only key, a trained automotive locksmith with the correct programming equipment can produce a fully working replacement at the roadside, in a car park, or on a driveway. The key is cut to the vehicle's lock profile and programmed to communicate with the immobiliser, so the engine starts normally. Remote locking is synchronised at the same time. The process involves OBD port access and communication with one or more control modules depending on the make, but it is something experienced mobile locksmiths handle as standard.
How long does key programming take?
Car key programming typically takes between 30 and 90 minutes depending on the vehicle make, model, and key type, with most jobs completed in a single attendance.
Simpler transponder keys for older Ford or Vauxhall models programme more quickly than smart keys for a BMW communicating through the CAS or BDC module. Drivers in Portsmouth asking for a time estimate will receive a practical window once we have the vehicle details. The job is completed in one visit in the vast majority of cases.
Can spare car keys be made on site?
Yes, Portsmouth Car Keys produces spare car keys on-site across the Portsmouth area, cutting and programming a working spare at the driver's location while the original key is still present.
When the original key is available, the programming sequence for a spare is significantly simpler. For drivers in Portsmouth, Gosport, or Fareham currently holding only one key, getting a spare produced before it's lost is strongly advisable. The cost and convenience difference between a spare made now and a replacement required after losing the only key is considerable.
Is roadside key replacement possible?
Yes, roadside car key replacement is available across the Portsmouth area, with Portsmouth Car Keys attending the driver's location to cut and programme a replacement at the roadside.
Drivers who have lost car keys, broken a blade, or locked keys inside a vehicle anywhere around Portsmouth can have a replacement produced without moving the car. Our mobile unit carries blank key stock for a wide range of makes and the programming hardware to pair that key directly to the vehicle's immobiliser. From Southsea seafront to the roads around Havant and Fareham, we attend the location directly.
