Car remote lock/unlock no longer working

This is how to reset the alarm Roll up all windows exit the car lock all doors with the remote, then wait ten minutes, unlock the door using the key, that will reset the alarm. without remote I found this, have no idea if it will work, but worth a try!!

this is a problem that can appear after your car battery died, cause the car didn't reset propely, so taking the battery out and putting it back in or letting your car die again would do the trick. I tried a lot of reprogramming procedured for my remote key, none of them worked, what did the trick though was simply unlocking the doors via the all door unlock button on the passenger side door, so simple.

My van is similar to your situation. I had the car alarm company who installed alarm reinstall a sensor and it worked for awhile..I have to get it done again or change whole alarm system/auto door locks altogether (update).. Good luck..

you need to reset alarm/immobiliser.lock car with remote, hold button down for 30 secs,then press/hold down unlock button,should reset.another way is with key in ignition/turned on, press alarm button down and hold for 30 secs.this resets immobiliser.toyota
systems vary..depending on market.

first check the battery in the remote. if it is good it could possibly be the body control module

If your car has an alarm with a separate remote, it is a separate system and it is probably self-arming. When you lock the doors with the key central lock, the alarm gets armed by the RAV4 being OFF and the door locking action. When you unlock the doors with the key, the alarm is still armed because the key is not comunicating with the alarm just the cars factory keyless system.

sounds like it's in theft mode?
try using the fob to lock and unlock the doors 3X then open the drivers door with the key
if that does not work use the kill switch
