Audi key work falls either side of a clear dividing line. On the older cars the usual culprit is a physical component in the ignition barrel; on the current range the obstacle is the car's own security architecture.

We work on both across Somerset, Wiltshire and Dorset, on-site, with a free quote before we arrive.

Older Audi key systems we work on

The early A4 range has one dominant, well-documented fault, and it is often mistaken for a fuel or starting problem.

  • On older A4 generations — B5, B6 and B7, roughly 1995 to 2008 — the immobiliser reader coil in the ignition barrel is a well-documented failure point
  • The symptom is intermittent starting where the engine fires and then cuts out again after a couple of seconds
  • Because the car does start briefly, the fault is easily blamed on something other than the immobiliser

Current Audi models we work on

On the modern range the key itself is only half the job — the car has to be persuaded to accept it.

  • Modern Audis use Component Protection, requiring dealer-level or specialist access to pair a replacement key or module
  • Current key fobs come in 'High' (Comfort Access) and 'Low' versions
  • The two versions are not interchangeable, so the correct one has to be identified before a key is supplied

What happens on the visit

We confirm the model and key version first, then establish whether the fault sits with the key, the reader coil or the pairing side of the system. Keys are cut and coded at your vehicle and tested on lock, unlock and ignition before we leave.

Common questions

My older Audi starts then cuts out after a couple of seconds — why?
On older A4 generations, the B5, B6 and B7 from roughly 1995 to 2008, the immobiliser reader coil in the ignition barrel is a well-documented failure point. When it fails the car starts intermittently and then cuts out again after a couple of seconds, because the immobiliser never confirms the key.
What does Component Protection mean for getting a new Audi key?
Modern Audis use Component Protection, which means a replacement key or module has to be paired with dealer-level or specialist access before the car will accept it. Cutting a blade alone is not enough — the pairing step is what makes the key work.
How do I know whether I need a 'High' or 'Low' Audi key?
Current Audi key fobs come in 'High' (Comfort Access) and 'Low' versions, and the two are not interchangeable. We identify which your car takes before supplying anything, so you are not left with a fob the vehicle will never accept.
