Hilux 4x4 Forum

Hi I hope someone here can help me. I will try and explain the problem the best I can.

My remote, key and door switch will not lock the doors, however they all unlock the doors. If I sit inside and manually lock all the doors and I use any of the three methods to unlock it works succesfully. However the remote does switch the alarm on and off.

Any assistance will be appreciated. Hope its a simple fix.

Regards,

Craig

The intergration relay unit needs replacing. It is the fusebox unit just below the steering covers

My issue is that this seems to be an intermittent problem and not happening all the time.

Thanks for the advice so far

Silly question, but isn't the battery in the key just flat?

Have you tried your spare key?

No same problem with key, remote and door switch
