Car Alarms: 2001 CHEVY SUBURBAN ALARM, dome light delay, chevy suburban

Question
MY CHEVY SUBURBAN ALARM KEEPS GOIN OFF EXACTLY EVERY 20 MIN? WILL START WITH KEY  BUT IF ALAARM GOES OFF WONT TURN OFF UNLESS U USE REMOTE TRANSMITTER N THEN STILL ALARM WILL GO OFF IN 20 ..CANT USE KEY IN IGNITION TO START N TURN OFF ALARM LIKE MANUAL SAYS. BATTERY SEEMS TO B GOOD N ALARM MADE A DOUBLE CHIRP STARTED ABOUT 1 WEEK AGO EVERYTIME WE LOCKED IT USING TRANSMITTER BUT STILL WORKED

Answer
Sounds like the alarm is detecting an open circuit.
Likely it's the dome light delay causing it.
Either wait for the dome light to go out
BEFORE you arm it, or get a local car alarm
shop to change the last door arming setting
for 1 min. override.

Good luck.
