Why Derby drivers choose SRM Auto Access for transponder coding
Every modern car has a transponder chip inside the key that talks to the immobiliser. If the chip isn’t correctly coded, the engine will crank but never start — a common surprise for drivers who buy a spare key on the internet and expect it to just work.
That is where we come in. Our mobile coding service pairs chip keys, remotes and modern smart proximity fobs to your car’s immobiliser on your driveway across Derby. Whether you have already bought a blank remote, need a spare cut and coded from scratch, or have lost every original key, we cover the full process on-site.
We cover almost every UK make and generation of immobiliser — from older fixed-code transponders to the latest AES rolling-code smart keys — with dealer-grade software carried in the van.

Chip keys, remotes, and smart keys — what’s the difference?
A basic transponder key has a chip in the plastic head and a mechanical blade. A remote adds lock, unlock and boot buttons that talk to the car by radio. A smart key adds proximity detection so you never take the key out of your pocket. All three need to be coded to the immobiliser to actually start the engine — the buttons and proximity features are separate but related.
Because manufacturers switch between generations of coding hardware (fixed-code, rolling-code, AES) even within the same model over the years, it helps to send us your registration first so we arrive with the right blank and cable.
When you might need transponder coding in Derby
The most common reasons for a coding callout: buying a spare key online, replacing a lost key, upgrading from one to two working keys, fitting a new ignition, replacing an ECU or immobiliser module, or after an all-keys-lost. Each of these is a normal weekly job for us.

FAQ
Frequently asked questions
What is transponder key coding?+
Transponder coding pairs the chip inside your car key to your vehicle’s immobiliser. Without correct coding, the engine will crank but not start. It is required whenever a new key, remote or smart fob is added to a car.
Do you code transponder keys on-site in Derby?+
Yes — SRM Auto Access codes transponder, remote, flip and smart proximity keys on your driveway across Derby using dealer-grade diagnostic hardware.
How long does key coding take?+
For most vehicles, 30–60 minutes on the driveway including a cut. All-keys-lost coding can take longer where an immobiliser reset is required.
Which makes do you cover for transponder coding?+
Almost every UK make — BMW, Mercedes, Audi, VW, Skoda, SEAT, Ford, Vauxhall, Peugeot, Citroën, Renault, Nissan, Toyota, Kia, Hyundai, Fiat, Land Rover and Jaguar.
My mechanic fitted a new ignition — can you code my key to it?+
Yes. We regularly finish jobs after ignition swaps by coding your existing key to the new barrel or immobiliser, no dealer visit required.
Can you clone a transponder key?+
For older fixed-code transponders, yes — cloning is often possible. For rolling-code immobilisers we program a new key directly to the vehicle, which is more secure.
How much does transponder coding cost in Derby?+
Far less than a main dealer, and always priced upfront. Send your reg to 07378 615444 for a firm quote before we set off.
