However I've been having an issue with the central locking on and off for two years now, and whilst in for MOT and service I told them about it and got them to try fix it, to no avail....The central locking works fine on all doors when i use my key in the drivers door (both locking and unlocking). But the key fob does not. I have bought so many fobs over the last 2 years, some work for a bit then die, but it's got worse and now no fobs will work. have tried swapping batteries, coding my fobs to someone else's van to check they work then coding them to mine, no luck, buying new fobs etc. When I enter programming mode, I click buttons on a fob and sometimes the van will make a 'clicking' noise as if it's trying to do something but cant, but sometimes nothing happens at all, and after 20 secs the locks cycle again to exit. Sometimes the fob will burst into life and work briefly, only to stop again. I've tried noting when this happens to see if there's a pattern, but there's no rules to it.
Have had battery checked, fuses, all the obvious things. Nothing came up in diagnostic checks. The only thing I can think that might be doing it is my back doors - they sometimes slip off the catch when I hit a bump, they don't open fully but remain 'locked' but an inch or so flapping around off the locking catch. the van still locks the other doors when this has happened if i use my key.
The garage suggested the next logical step is to buy a replacement lock unit and catch for the rear doors, try that and see if it fixes the locking issue. But I'm dubious that's it as the fob still won't work even when I've ensured the back doors are shut properly.
Has anyone got any ideas? Am trying to to throw infinite money at it but I'm running out of options. ideas for how to fix the back doors and/or fix the general central locking would be great
