Hey guys, I am having a problem with my factory alarm. I put the key in the door to lock it and turned the key the opposite direction. The alarm engaged and I tried everything to disengage it to no avail. Finally I had to pull the battery cable off. The next morning I hooked the battery back up and the alarm continued. Need some advice on how to handle this situation. Also, can I just disconnect the siren from the alarm and it still operate for the horn on the steering wheel. What does it entail to get to the rear of the lock cylinder if it needs replacing or wiring repaired. Thanks for your assistance.
