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 creates an immediate problem. Portsmouth Car Keys carries programming hardware and blank key stock, allowing us to produce working replacement keys on-site for a wide range of vehicles. 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 programming process too, checking that the replacement operates correctly before completing the callout.
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.
Our mobile response brings specialist non-destructive entry tools directly to your vehicle, wherever it is safely accessible. These 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. Tell us your location and vehicle details when calling so we can advise on attendance.
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 vehicle, the process may require communication with the Body Control Module (BCM), Engine Control Module (ECM), or a dedicated immobiliser module. Many vehicles support programming through the OBD port; others require additional module work. BMW systems, for example, vary between CAS, FEM and BDC modules according to model and year. We confirm compatibility and use the appropriate procedure to produce a working key.

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, for most supported vehicles.
Losing the only set of keys means there is no recognised key available to authorise starting, even if the vehicle is unlocked. We attend your location, generate a new key with the correct transponder, and pair it to the immobiliser so the vehicle starts normally. Whether you're at home, at work, or parked near Gunwharf Quays, the Historic Dockyard or anywhere else on Portsea Island, contact us with the make, model and year so we can explain the options.
Keys Locked Inside the Car
Drivers who have locked their keys inside their vehicle in the Portsmouth area can contact Portsmouth Car Keys for non-destructive entry using specialist automotive tools.
Getting the door open without damage is the immediate priority. We select an entry method appropriate to the vehicle, using specialist lock-opening equipment or automotive access tools where suitable. Care is taken to protect the weatherstripping, locking mechanisms and paintwork throughout. If the keys are simply locked inside and remain functional, a replacement may not be needed. We can retrieve them and check that you can lock, unlock and start the vehicle normally.
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 may no longer operate the lock reliably. A snapped blade inside a door lock or ignition barrel requires extraction before a replacement can be used. We carry automotive extraction tools and can supply a replacement once the fragment is removed. Where a remote flip key has split from its blade, a shell rebuild may be possible while retaining the working electronics.
Faulty Remote Key Fobs
A faulty car key fob may require battery replacement, re-synchronisation, or a replacement remote, which Portsmouth Car Keys can diagnose at your location.
A flat battery is the simplest cause, but a fob that won't respond with a new cell needs further investigation. Lost synchronisation, damaged buttons, signal interference or internal component failure can all affect operation. Remote locking and immobiliser functions are separate on many keys, so a failed remote does not necessarily prevent starting. We diagnose the fault before recommending a repair or replacement, helping you avoid paying for parts you don't need.

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 availability.
Call 023 9299 0167Why a Mobile Auto Locksmith Is the Best Option
Fast Local Response Across the Region
A mobile auto locksmith can provide a faster and more cost-effective option than a dealership or recovery service for many car key emergencies across the Portsmouth area.
Dealership replacements may involve ordering a key and arranging an appointment, while recovery adds transport time before work can begin. A mobile locksmith travels directly to you with tools and key stock onboard. We regularly cover Portsmouth and nearby towns via the M27 and A3(M), with attendance depending on your location, traffic and current bookings. We'll give you an estimated arrival time when you contact us.
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 matters. Modern key programming requires compatible hardware, software and security procedures, rather than a simple copy of the blade. Different vehicles use different systems, including Vauxhall BCMs, Citroen and Peugeot BSI modules, and Mercedes EIS units. Our equipment supports a broad range of makes, and we check the exact vehicle specification before confirming what can be completed on-site.
Convenient Mobile Service for Drivers
Portsmouth Car Keys attends the driver's location for auto locksmith services, covering homes, workplaces, car parks, and accessible roadsides across the Portsmouth area.
The car often can't move when a key problem occurs, making a mobile service particularly useful. You don't need to arrange alternative transport just to have the vehicle assessed. For businesses running fleet vehicles, prompt attention can also reduce downtime. We carry key stock for common commercial vehicles, including Ford Transit, Vauxhall Vivaro and Fiat Ducato models, with compatibility checked against the vehicle's age and specification.

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 produced while a working key is still available is often simpler and more affordable than replacement after losing every key. The procedure depends on the vehicle, but having an existing key can reduce the work involved. We produce spares 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 many vehicles.
We replace damaged or missing remotes, cutting the blade where required and programming the immobiliser and remote functions. Proximity-based smart keys need equipment compatible with the vehicle's security system. Porsche and Land Rover systems differ by model and year, so we check support before confirming a replacement rather than assuming one programming method suits every vehicle.
Broken Key Extraction
Portsmouth Car Keys carries out broken key extraction from door locks and ignition barrels, removing snapped fragments before supplying a replacement key where needed.
A blade fragment can prevent another key from entering or turning properly. Our extraction tools are purpose-built for automotive locks, allowing fragments to be removed without drilling in many cases. We also check for wear or damage that may have caused the break.
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 matched to existing keys where possible.
Ignition faults and key faults can appear similar, so diagnosis comes first. A worn barrel may need repair or replacement. Where its construction allows, we match a replacement barrel to the existing key, avoiding an unnecessary change of keys.
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.
We support many popular Ford models, from Fiesta to Transit. Nissan Qashqai and Juke systems vary by year, while newer Toyota models often use smart keys. Programming requirements depend on the exact security system, so we confirm the model, year and key type before arranging the work.
BMW, Audi and Mercedes Models
Portsmouth Car Keys replaces and programmes keys for supported BMW, Audi, and Mercedes vehicles using compatible tools, including smart keys and remote entry systems.
BMW CAS, FEM and BDC systems require different procedures. Audi immobiliser arrangements also vary, while Mercedes EIS systems need a correctly matched key. We check each vehicle individually because coverage and replacement methods differ between generations, even where the keys look similar.
Volkswagen, Hyundai and Kia
Car key replacement for Volkswagen, Hyundai, and Kia vehicles is available from Portsmouth Car Keys, with on-site programming for supported transponder and remote entry systems.
Many Volkswagen models support diagnostic-port programming, although some require additional security-data procedures. Hyundai and Kia systems also vary across model years, including the Tucson and Sportage. Citroen, Peugeot and Mazda are among the other makes we support; provide your vehicle details when enquiring.
