Hi

My Mazda 3 Neo 2011 Locking system is playing up from time to time. I have had it at the mechanic's but they are unable to diagnose as the issue never happens when the car is there.

When I go to lock the car it will make a different noise to the normal locking sound like its locking and unlocking straight away. Sometimes if i hit the unlock button and then press the lock button it will then work otherwise i have to open and close doors to try to get it to lock.

Other times the light on the fob will light up that its working when I press the button but the car doesn't respond at all.

any ideas ??
