Every listing in this shop is a send-in postal service. Once ordered, we email you packing instructions — the private workshop send-in address is shown on your order page and in your confirmation email — only to paying customers. Most jobs are completed and returned same-day on arrival, fully tracked.
Prefer we come to you or drop the vehicle in? Request a quote — mobile service is available across the West Midlands with a call-out fee based on your postcode.
Call-out fees are guidance only — confirm your postcode when requesting mobile attendance. Postal send-in has no call-out fee.

Frequently Asked Questions
Do I have to remove the CAS module?
For the postal service, yes. Choose mobile service if you would rather we attend the vehicle.
Will my existing keys still work?
Yes on an add-key job. On all-keys-lost, old keys are deleted for security.
Why do you need the ECU for all keys lost?
The ISN is stored in the DME. We read it there to write matching keys into the CAS.
How fast is turnaround?
Most CAS3 jobs are completed the same day they arrive and returned tracked next-day.
