Hi
For the factory alarm , Disconnect the battery
Turn the key to the on position
Reinstall the negative terminal
the alarm indicator in the display will show 20 minutes
and begin to count down
The alarm horn will sound for 5 minutes and then stop
continue the count down for 15 minutes
you should then be able to start the car
there is no turning it off
update when possible
Please remember to accept and rate as a positive
or I receive no credit for my response
Thanks
