2001 Yaris TSport Central locking issue

[Christina84]

Hi everyone , I'm wondering if anyone has had similar problems with their Yaris.

I'm not sure if this is a coincidence but since my car went for it's MOT whenever the weather is cold and wet ( like today!) my central locking plays up

It's fine when I want to get in to the car for the first drive parking and locking , but when I get back to the car the central locking doesn't work. My only option is to unlock the car manually with the key, which sets the car alarm off, and the only thing I can do to get the alarm to go off is start the car and within 30 seconds it's deactivated.

I'm wondering if this is a damp issue? I have 2 keys and it doesn't seem to matter which set I use same result.

Thanks :)
