Quick answer
Repair wins when the electronics are healthy: worn buttons, cracked cases and loose battery contacts are cheap, quick refurbishment jobs — new case, new buttons, done in about half an hour. Replacement is the honest answer when the circuit board is damaged, usually by water, or when faults are erratic and untraceable. We inspect the board under magnification before advising, so the recommendation is based on evidence, not guesswork.
When repair is the right call
If every function works but the fob looks and feels knackered — worn-through buttons, a cracked or split case, rattling battery contacts — the electronics are fine and only the wear parts need renewing. Refurbishment transfers your working board into a new case with new buttons. It's quicker, keeps your original programming, and costs less than a replacement fob plus coding.
When replacement is honest
Water damage is the main killer: once corrosion gets under the components, the board is unreliable even if it seems to work now. Erratic, unrepeatable faults — works Tuesday, dead Wednesday — are the other sign of board-level failure. In these cases we'll say so and supply a replacement fob, programmed to your car, rather than charging you for a repair that won't last.
The cost logic, without the hard sell
We won't put £ figures on a website because the honest answer depends on the fob, but the logic is straightforward: refurbishment costs less than a new fob plus programming, and it avoids recoding entirely. If repair is viable we'll say so — we're not in the business of selling you electronics you don't need. We quote on the phone before we set off, so you can decide with the facts in hand.
A quick decision checklist
Run through these before you call:
- All buttons work but the case/buttons are worn → repair
- One button dead, rest fine → repair (worn switch or pad)
- Washed, soaked or dropped in water → likely replacement
- Works sometimes, no pattern → needs inspection, often replacement
- Fresh battery changed nothing → diagnosis needed
What refurbishment involves
We open the fob, inspect the board for corrosion and cracked joints, clean the contacts, and move the board into a new case with fresh buttons and a battery. Then we test every function at the car — remote locking, boot release, keyless entry and start. About 20 to 30 minutes, done in the van at your location.
Related questions
Can you repair a fob I bought online?
We'll look at it, but cheap online fobs are often poor copies with fragile boards — sometimes they aren't worth repairing. Bring it and we'll give you an honest assessment.
Does a refurbished fob need reprogramming?
No — it keeps your original circuit board and programming. Only a replacement fob needs coding to the car.
My fob works after being washed. Am I in the clear?
Not necessarily. Corrosion can develop slowly over days or weeks. Get it checked sooner rather than later — early cleaning can save a board that later corrosion will kill.
