I have a MY02 WRX with Sigma M30 alarm retro-fitted.

Just recently the following happens and wonder if anyone can explain....or offer advice to a solution.

The keyfob disarms the car, i then drive a short distance, get out and use the keyfob to arm the car (this take a couple of presses on the keyfob). I can then no disarm the car for 30minutes or so.

Basically nipped to the Post Office last weekend, came back to the car and could no disarm, walked back home and then back to the car and it disarmed 1st time, then went to the supermarket (armed the car), bought some shopping and came back and car disarmed 1st time.

Same thing this morining on way to work, stopped for some milk then had to wait 30mins for the alarm to reset.

Any ideas ?

Thanks

 

probably needs a new battery in the remote.
