Proton vehicles built from 1996 onwards use transponder immobiliser technology for added security. Earlier models commonly used Texas 4C fixed-code transponder chips, while many vehicles from around 1998 onwards upgraded to Temic Crypto 8C rolling-code systems that generate changing security data each time the vehicle starts.

Can you replace my Proton key if all keys are lost?
Yes. We can usually supply, cut, and program replacement Proton keys even in complete all-keys-lost situations. Our mobile auto locksmith specialists use advanced diagnostic equipment to program new transponder keys directly to the vehicle immobiliser system at your location.

If your Porsche has self-locked with the keys inside, our locksmiths use specialist non-destructive vehicle entry techniques and professional lock-picking methods designed for high-security vehicles. In many cases, we can safely unlock Porsche models within minutes without damaging the locks, doors, or windows.
Why does Porsche key programming require specialist equipment?
Porsche vehicles use highly advanced encrypted immobiliser and transponder systems that require dedicated Porsche diagnostic software and specialist programming tools. Many Porsche keys must be pre-coded specifically to the vehicle before programming can begin, and some models require advanced bench programming procedures carried out inside our fully equipped mobile locksmith vans.
Can you replace Porsche keys if all keys are lost?
Yes. Even in complete all-keys-lost situations, we can usually supply and program replacement Porsche keys at your location. Depending on the Porsche model, we may extract immobiliser and transponder data directly from the BCM (Body Control Module), PAS (Porsche Alarm System), or vehicle immobiliser memory to program a new working key without dealership delays.
Do Peugeot remote fobs control the alarm and immobiliser system?
On many Peugeot models, yes. From around 1998 onwards, Peugeot remote fobs often controlled not only the central locking system but also the factory alarm and immobiliser functions. Correct programming is essential to ensure the remote key communicates properly with the vehicle’s ECU and security system.
What type of immobiliser systems do Peugeot vehicles use?
Peugeot vehicles built after 1997 use transponder immobiliser systems designed to improve security and prevent hot wiring. Earlier systems commonly used Philips type 33 fixed-code transponders, while later models introduced advanced rolling-code systems such as Philips type 45 and type 46 (T14) chips, which generate changing security data each time the vehicle starts.
Can you program replacement Peugeot keys if all keys are lost?
Yes. Even in complete all-keys-lost situations, we can usually supply, cut, and program replacement Peugeot keys at your location. Most Peugeot models require a vehicle security PIN code for programming, and if the original security card is missing, we can often retrieve the immobiliser PIN directly using specialist diagnostic equipment without dealership involvement.
Do you provide replacement Nissan remote fobs and emergency vehicle entry?
Absolutely. We supply and program replacement Nissan remote fobs, integrated immobiliser keys, and smart key systems for most Nissan models. If your Nissan has self-locked with the keys inside, our locksmiths use specialist non-destructive entry techniques to safely unlock the vehicle without damaging the locks, windows, or bodywork.
What types of transponder and immobiliser systems do Nissan vehicles use?
Nissan vehicles built from 1995 onwards use transponder immobiliser systems for added security. Earlier models commonly used Philips type 33 fixed-code transponders (T5 chips), while later vehicles introduced rolling-code crypto systems including Philips type 41, Texas Crypto 4D, and Philips Crypto type 46 transponders. These systems generate changing security codes every time the vehicle starts, making unauthorised duplication far more difficult.
