Frequently asked questions

Do I get my own unit back?

Yes. This is a repair, not an exchange — we repair and return your original unit, so it keeps the coding and security data already matched to your car and needs no programming afterwards.

How long will I be without the unit?

We aim to complete all repairs within 2–5 working days. Should a repair take longer, we will contact you with an update. It goes back to you on a tracked service. Ask about on-site fitting if you need the car back the same day.

My part number isn’t in the list — can you still help?

Usually yes. The same hardware appears under many part numbers. Send us a photo of the label or call 01884 798090 and we’ll confirm before you send anything.

What warranty do I get?

Repairs carry a 24-month warranty. See Returns & Warranty for the full terms.

Will the warning light go out after the work?

Yes, once the unit is refitted and the stored codes are cleared, provided the fault was in this unit. If a related wiring or sensor fault is also present it has to be fixed separately — we tell you what we found.
