Hi guys I have a 2003 Toyota Camry le 4 cylinder just installed new battery for the past days the alarm has been going off at night , before I installed the new battery it would go off , and now with the new battery it just beeps at night like if the alarm wants to go off, I noticed the problem when a red and black wire with a small red dot light by the drivers side fell off the wires I found where it was connected and took it off but the alarm keeps going off, if anyone can tell me how I can disable the alarm completely either  by disconnecting a fuse or something I would appreciate it , also the key fob still works I haven’t replaced the battery though.

The Alarm is part of the anti-theft system, you can not simply remove a fuse to disable it.

The first thing you can do is to change the key fob battery. If that didn't fix it, make sure all the doors (including trunk) are completely shut when you lock the car.


All doors are closed , you think the alarm system reset after I unplug the battery?


It does not need reset. The keyfob might be faulty and does not transmit correctly.


Is the alarm factory or after market?


Pretty sure is factory also the key fob is from Toyota, could some how when I changed the battery reset or something happened to the alarm during that short period ?


The key fob works to lock and unlock unless it’s damaged and causing the alarm but somehow still works ? Just like my old battery it was a bad battery but it would still turn the car on I didn’t know it was bad til the alarm started going off so I just changed the battery


I suspect that the key fob is faulty. The older Toyotas came with two key fobs. Do you have another on to try?


No I only have one and one key does that mean I need to buy a new key fob if replacing the battery on the current one doesn’t work ? Or will I need to take it to a mechanic to program the new key fob once I buy it.


You can program keyfobs yourself. Google for your car and you will find the procedure.
