  1. Luis, it sounds like either the alarm is malfunctioning, the remote has not been programmed correctly or there is a problem with the antenna communicating with the remote. Try checking the alarm module itself. Make sure there is power going to it and the antenna wire is plugged into the alarm module snugly. If this does not solve the problem, we suggest you take your car to an experienced audio installer and have them troubleshoot your problem. Hope this helps. Good luck with your 2005 Toyota Sequoia alarm troubleshooting.

  2. My 2004 toyota sequoia alarm is not working…. I pressed the lock/unlock buttons and the green light comes on but it will not chirp or lock or unlock doors. I replaced batteries on both alarm remotes, i tried reprogramming twice and no go…. Please help as I have to insert the key every time i have to open and lock doors. :)

  3. Kristin, as much as we would like to help you, not all car alarms are installed the same way. Different brands and different setups will call for different wiring. Our advice is to take your car to a qualified alarm installer and ask them how to disarm the alarm because it does take some wiring knowledge and experience to know what to do. Hope this helps. Good luck on your 2005 Toyota Sequoia alarm troubleshooting.
