I NEED A SPARE KEY FOR MY CAR OR VAN

Master Auto Locksmiths, in Portsmouth are equipped to cater for 95% of spare keys for your car or van. We carry stock for the most popular vehicles and have next-day access to more obscure keys and remotes. Operating a mobile service supplying ‘spare car keys’ and ‘spare van keys’ in the Portsmouth and Hampshire area, Master Auto Locksmiths are a convenient option. The majority of automotive key-cutting and programming operations are carried out on-site, at your home or place of work. We operate a wide bandwith of scheduling 7 days per week, offer emergency call outs and arrange unsociable hours visits, if required. 

High-Quality Car, Van, & Remote Keys

Many car and van remote keys can be catered for with high-quality, programmable automotive remote car key systems. These remote keys can be programmed to match the transponder and remote logic of a wide range of manufacturers and vehicles. They are cheaper than genuine manufacturer keys and last just as well if not longer. However, a small percentage of vehicle keys need to be of a genuine type supplied by a main dealer. A very small minority of these can only be programmed by main dealer tools.

Mobile Auto Locksmith Operating On-Site Car or Van Key Cutting & Programming in the Portsmouth & Hampshire Area

In most cases, keys are cut and assembled on-site for the customer – and programmed into the vehicle’s immobiliser. Varying methods are used to program keys into a vehicle’s security system. Some are straightforward and some are very complex. Most programming operations can be completed via the onboard diagnostic socket (OBD).

Car & Van Key Programming Requires a Healthy and Fully Charged Vehicle Battery

The process of car and van key programming requires a healthy and fully charged car battery. During automotive key programming, if the battery charge level is low or a battery is in poor health, this can cause serious issues during immobiliser programming, so it is important to make sure that your vehicle’s battery health is good, before booking an auto locksmith.

Master Auto Locksmiths carry provision to provide battery testing & battery charging services. Please note that these services take extra time, and are provided at an additional cost.

Battery Support For Sensitive Immobiliser Key Programming

Some vehicles, typically later vans and some later cars are susceptible to voltage issues during immobiliser key programming. When the voltage is too low, immobiliser key programming can go very wrong, very quickly. These vehicles require a higher voltage than a 12v battery will supply, similar to an alternator voltage. Master Auto Locksmiths carry professional-grade automotive power supplies – often used for ECU remapping and diagnostic work, to hold the vehicle voltage at a stable 13.2v or higher, during key programming.

Diagnostic Fault Codes & Vehicle Key Programming

If a vehicle has DTC codes stored on computer modules as a result of historic or current faults on the vehicle, these codes can hamper key programming particularly if the faults are current and active.

I NEED A SPARE KEY FOR MY CAR OR VAN


If you have an existing key and need a spare, we can visit you in Portsmouth or any location in Hampshire. We arrive with your key ready-cut if the key code is available, or decode the key on-site ready for cutting. We scan the existing key transponder for information. 

Once new key blades are cut and tested for operation in the locks, a key head is fitted in the new key. A matching ignition transponder is fixed into the key head, which communicates with the ignition transceiver when the key is inserted into the ignition, which, in turn, should disengage the immobiliser to start the vehicle.

Car Key Cloning

Sometimes we can clone your original car key or van key transponder to a new transponder, ready for fitting into a newly cut car key. The cloning method is the safest way to make a new car key, as there are no intrusions into the immobiliser via the OBD port required to do this.  If the transponder is unclonable, we can set a new transponder to the correct ID for the vehicle and program the key into the vehicle’s immobiliser, via the OBD port.

If the locks on your vehicle are common, have not been changed and are in good working order, the new key will unlock the doors and operate the ignition.

The transponder in the key head is programmed into the vehicle’s security system, authorising the key to start the vehicle.
