🔑 YOUR CAR KEY STOPPED WORKING? HERE'S WHY 🔑
We were called out to a customer in Southampton whose key fob had suddenly stopped unlocking his car. No physical damage and no warning. It just stopped responding.
A quick check showed the key's internal transponder chip had failed. A common fault on older keys, especially ones that have taken a knock or been near water. New key programmed and working within the hour.
✅ Transponder and remote fob faults diagnosed on the spot
✅ Replacement keys supplied, cut, and programmed in one visit
✅ No dealership needed. Faster turnaround and lower cost.
Car keys fail more often than people realise. If yours has been playing up, don't wait until you're fully locked out.
