It didn't come with a remote... not a keyless system. It comes on automatically after the last door is closed when the doors are locked. There is a sensor in each of the three lock cylinders to arm and disarm it. in '91 and '92 the system was built a little differently and a keyless module was offered by Toyota which just plugged right in.


If you don't see the light on the dash labeled "Security" light up then the alarm is not arming... this is due to one of three things usually: bad lock sensor, bad trigger sensor (doors, hood and hatch) or it's been disabled on purpose.
