Factory Alarm Arming Problems
 

Hi!
2002 Sebring Convertible, i got problems with a factory installed alarm (keyless entry).
50%of locking the vehicle is failed - alarm is arming for 15 seconds andfinally fails to arm - lights goes on, horn, etc...
in other 50%of attempts everything is ok andalarm is armed.

Question - sensors, battery, anything else?
Where are there sensors installed infact?
I'm trying to findwirediagram,anything could help.. (dealer is last option -i got long distance tonearest location).
