Frequently Asked Questions
Which chassis option should I pick?
Choose the family that matches your car and enter your registration — we confirm the immobiliser generation and tell you exactly what to post before you send anything. If in doubt, pick the closest option and we will correct it for you.
What do I post to you?
For an add key: the EIS plus one working key. For all keys lost: just the EIS — no key and no ECU needed.
Where do I send it?
As soon as you order, we email your packing instructions and the send-in address, with your order number to write on the note inside the parcel.
Is the ESL emulator ready to fit?
Yes. We pre-code the emulator to your own EIS and key on the bench, so it plugs straight in with no coding at the car. £100 alongside a key job, £180 on its own.
How quickly do I get it back?
Most jobs are done the day they arrive and returned on a tracked next-day service.
Can you come to the car instead?
Yes — choose mobile call-out on this page. We cover Wolverhampton and the West Midlands, with the call-out fee confirmed for your postcode before we set off.
Not sure your car is compatible?
Send your VIN and we'll confirm compatibility before you order. We cover CAS1, CAS2, CAS3, CAS3+, CAS4/CAS4+, FEM/BDC and BDC2.
