Auto Locksmith Lee-on-Solent – Mobile Car Key Replacement & Vehicle Locksmith

Replacement Keys When the Original Is Lost

Portsmouth Car Keys replaces lost car keys in Lee-on-Solent at the driver's location, generating a new transponder key and programming it to the vehicle's immobiliser even where no spare key exists.

Losing the only key creates a technical problem beyond being unable to unlock the door. Without a recognised transponder, the immobiliser remains active and the engine will not start regardless of how the vehicle is accessed. We resolve this using the appropriate security access and programming procedure for the vehicle. This may involve communicating through the OBD port or accessing the relevant control module directly, depending on the make, model, and security system.

In most cases, remote locking functions are synchronised in the same visit, so the driver receives a complete working key rather than one that only operates the ignition. We also check proof of ownership or authorisation before proceeding.

Vehicle Entry Without Damage

Portsmouth Car Keys opens locked vehicles in Lee-on-Solent using specialist non-destructive entry tools, with methods chosen to protect door seals, locking mechanisms, and paintwork.

Professional vehicle entry starts with selecting a method suited to the car's locking system. Specialist lock-picking tools can provide access through the door lock, while carefully controlled air wedges and reach tools may be appropriate for some vehicles. Deadlocking and other security features affect which technique is suitable. We avoid forcing the door or lock, and once access is restored, any necessary key or remote programming can usually be completed during the same visit.

Emergency Lockout Help

Portsmouth Car Keys provides emergency lockout assistance in Lee-on-Solent for drivers locked out of their vehicles, attending promptly with specialist non-destructive entry equipment.

Whether you're outside your home or stranded in a car park, a lockout can disrupt the rest of your day. We attend your location and assess the safest way to restore access. Let us know whether the keys are visible inside, locked in the boot, or missing altogether, as this helps us prepare for the callout.

Lost Keys Away from Home

Lost car keys in Lee-on-Solent can be replaced on-site by Portsmouth Car Keys, with a new key cut, programmed, and paired to the vehicle at the driver's location.

Discovering your keys are missing after shopping on the High Street, a walk along Marine Parade, work, or an appointment can leave you unsure what to do next. If no spare is available, we can attend the parked vehicle and produce a replacement. We identify the correct key type, gain access where necessary, and programme the new key to the immobiliser. You don't need to know exactly where the original was lost to arrange help.

Keys Locked Inside the Vehicle

Portsmouth Car Keys attends locked vehicle callouts across Lee-on-Solent using non-destructive automotive entry tools, with techniques selected to protect locks, seals, and bodywork.

Keys locked in a car are one of the most common reasons drivers call us, and it rarely happens at a convenient time. A fob left on the driver's seat or a key shut inside the boot can prevent access even though the key itself works perfectly. Tell us where the key is and whether the vehicle has deadlocked. We assess the locking system and use an appropriate entry method rather than forcing access.

Broken or Damaged Car Keys

Portsmouth Car Keys provides broken car key repair and replacement in Lee-on-Solent, including extraction of snapped blade fragments from locks and ignition barrels and on-site key programming.

Repeated use, a worn lock, or a damaged key blade can eventually lead to a break. Removing a fragment from an ignition barrel requires purpose-built extraction tools and care around the internal wafers. Once the fragment is clear, we inspect the lock and supply a replacement blade or complete key as required. If the original transponder remains usable, it may be possible to retain it. Attempting extraction with improvised tools can push the fragment deeper or damage the lock.

Remote Key Fob Issues

Portsmouth Car Keys diagnoses and resolves remote key fob problems in Lee-on-Solent, including synchronisation faults, keyless entry failures, and issues involving supported vehicle security systems.

A remote that stops responding isn't automatically a write-off. A depleted battery, damaged buttons, or lost synchronisation may explain the fault, and replacement of the whole key isn't always necessary. Remote locking and immobiliser functions are separate, so a failed remote can sometimes still start the engine. On proximity-entry vehicles, the problem may lie with the vehicle's receiver, antennas, or security module rather than the fob. We diagnose the cause before recommending parts or programming, including checks on supported Kessy and BCM2-equipped vehicles.

Spare Car Keys Made On Site

Portsmouth Car Keys makes spare car keys on-site in Lee-on-Solent at the driver's location, cutting and programming a fully working spare for supported vehicles.

The best time to arrange a spare key is before the original is lost. Having a working key available can simplify the process and avoids the additional work needed to gain entry when all keys are missing. The exact programming procedure depends on the vehicle's security system. If you've recently bought a used car with only one key, arranging a spare is a practical precaution. We can explain the available key options and provide a quote before booking, so you know what the spare will cost.

Remote Key Programming

Portsmouth Car Keys programmes replacement remote car keys in Lee-on-Solent, covering remote flip keys, smart keys, and proximity entry fobs for most vehicle makes and models.

A failed transponder can prevent the engine from starting even when the remote buttons still work. We supply and programme suitable replacement keys, cutting any mechanical blade and configuring the immobiliser and remote functions as required. These may involve separate procedures, depending on the vehicle. Our service covers many Fiat, Nissan, Mazda, Toyota, and Hyundai models, among others. Compatibility varies by model year and security system, so we check your vehicle details before confirming availability.

Broken Key Repairs

Portsmouth Car Keys carries out broken key repair in Lee-on-Solent, including blade extraction from door locks and ignition barrels and full key replacement where repair is not possible.

Where a remote flip key has separated at the hinge but the internal electronics remain undamaged, a shell replacement may avoid the cost of reprogramming. A snapped blade may also be replaceable while retaining a working transponder. If the chip or circuit board is damaged, a complete replacement may be necessary. We assess the condition before starting work and explain the options clearly, so you understand what can be reused and what needs replacing.

Ignition Lock Repairs

Portsmouth Car Keys carries out ignition lock repair in Lee-on-Solent for worn, jammed, or damaged ignition barrels, with replacement barrels matched to the existing key wherever practical.

A barrel that turns stiffly or intermittently fails to release the steering lock may have worn internal components, but the key itself can produce similar symptoms. An immobiliser warning may instead point to the transponder, reader antenna, or another electrical fault. We identify the source before recommending work. Where a barrel replacement is needed, it may be possible to match the replacement to the existing key, avoiding an unnecessary change of key set. Electronic ignition and steering-lock systems require a different assessment.
