Ive read a few posts after searching but just want to clear a few things up.
Sent my alarm last night and after 2 mins the alarm was going off, thought nothing of it (unlocked - relocked) and it stopped.
This morning locked my car for work and about 2 mins later the alarm is going off again
Ive read that it could be the powersounder but I just want to make sure.
The alarm is using the HORN and SIREN.
Is it just a case of buying a new one making sure the ignition is on (ie all lights on the dash but not the engine on) and pulling it out and replacing with a new one.
