Remote central locking has stopped working - what is the solution?
« on: September 11, 2018, 11:21:18 PM »
I have a 2008 1.6 petrol Mazda 3.

About two years ago the remote central locking/unlocking stopped working for BOTH key fobs.  I have had to physically insert the key into the door lock ever since (with which I am getting tired).

I have replaced the key batteries, cleaned the contacts within the remote fob, and tried to 're-programme' the keys, with no success.  "Re-programming' always fails to respond at the 'press any button on the fob" stage.

Is there any solution to this issue?   

Do I have to go back to the (hated) dealership, and will/can they actually guarantee that a new *remote* key will work?   

Can I go to an independent auto locksmith and will/can they also guarantee that a new *remote* key will work?

Possibly silly, but have you tried from the passenger door. Could be the receiver in the car door rather than the key? FWIW if wisdom knows there's a central receiver not one in each door don't flame me just thinking out loud.

Did you solve this problem?

I have pretty much the same issue.  My suspicion is that the receiver box in the car has gone bad, but finding any details is virtually impossible.

I bought a third key fob off ebay, programmed that and still had the same issue of intermitent door lock/unlock and alarm switch off.

I also have a local dealer that I avoid due to bad customer service.
