From an A3 on a Wimborne driveway to a Q5 in a Poole car park, Audi keys need the right immobiliser knowledge. We cut and program keys for many Audi models at the car, by appointment, including MLB-platform vehicles that some locksmiths avoid.
Audi shares much of its key technology with Volkswagen, but its larger models use the more secure MLB platform.
Audi owners across Bournemouth, Wimborne and Ferndown often contact us after being told the car must be taken to a dealer and left for days. For many models we can do the same programming on your driveway or at work. Smaller Audis such as the A1 and A3 are usually more straightforward, while MLB models like the A4, A5 and Q5 involve extra preparation and module work. Either way, we explain what your Audi needs in plain English, confirm the fixed price, and test every function before leaving – locking, unlocking, starting and, where fitted, keyless entry. If you still have one working key, a spare is well worth arranging now. Older Audis show the biggest savings against the dealer.
Immobiliser 4
The A3, A4 and TT of the 2000s and early 2010s. Key data is held in the instrument cluster.
MQB (A3 and smaller)
The newer A1, A3 and Q2 use the same platform as the Golf Mk7, with stronger encryption.
MLB and MLB Evo
The A4, A5, Q5 and Q7 use the MLB platform. Programming is specialist work, often involving the comfort module.
Advanced Key
Audi’s keyless system. The car detects the key nearby for entry and push-button start.
How much does a Audi key replacement cost?
A lost Audi key costs £220–£470 on average and a Audi spare key £170–£310, depending on the key type and model year. Newer VW, BMW and Land Rover spares are typically £350+, and some newer prestige models cost more. We confirm a fixed price from the model, year and registration before booking.
Audi dealer or auto locksmith – which is better?
A Audi dealer may need the car brought in and the key ordered. A mobile auto locksmith cuts and programs the key at your car in one visit. Audi spare keys typically cost 30–60% less than a main dealer, with the biggest savings on cars up to 2013. We quote a fixed price first.
Practical takeaways
Have the Audi model, year and registration ready.
A spare costs far less than a lost-key job.
Ask whether lost keys can be removed from the car.
Audi key situations
MLB all keys lost
Some A4, A5 and Q5 models need module work when no key remains. We check support before booking.
Cracked key cases
Audi flip keys wear at the hinge. A new programmed key is often the best fix.
