For your case, how long did TC install the alarm? Which one did you go to? Ubi?
I went to the Bkt Timah branch around 2.30pm
The service person says luckily the installer guy was there already. So can fix on the spot.
Otherwise need to call that guy to come down. Probably they outsource the service ba.
With service & alarm installation, BT manage to call me at 6pm to collect my car.
No manual given

so u better ask the service guy to demo when you collect your car

They can ask other service engineer to attend to you if you wan certain feature changed
