Hi, everyone i am new in forum and sorry my english; I have 87 xj laredo and 91 xj limted. My 2 cars are %100 original they'r not modificadet 91 limited as my avatar picture. İ have little problem on my 91. It has a factory security alarm system. I have original keyless remote and i used it. It works fine. Normally i lock the doors with keyless everyone is ok the security light flashes 15-20 sec. But some times the security light is lighitng continuous not flash. I look my owners manuel and it says "if the security light continuous lighting the system has a problem." When i see this problem i pull and wear the main battary jack problem was fix momentary. So 91 xj security system was disabled from the trunk door lock. I lock the doors with keyless and security system is active i unlock and lock trunk door and disable system every time that is so bad. I'd appreciate if you could help Thanks...
