I have a 1997 Cadillac catera. I tried to use my remote to unlock it, it did not work! I then used my key an the alarm went off, I started the car and it was still going off. So now everytime I go to open my door getting in or out, it goes off. Now I did think of my remote and did replace the batteries!! Still did not work.

SOURCE: My car alarm is blinking

you can try switching the key to the "on" position then open the hood and disconnect the negative terminal of the battery and reconnect after 2minutes. this will allow the alarm to be '"reset" and will recognize that you have the key for the vehicle.

SOURCE: my jaguar x-type 04, remote lock does not work,

Hi,

I have a similar problem in my x type. Although if I press unlock button on the key first and then use the metalic key to unlock it dissables the alarm.

Also according to the manual if you unlock by the metalic key the car starts a beeping sound its I think 15-20 second timer within which you should put the key and start the ignition (don't need to start the engin) this will dissarm the alarm if not the alarm will go off in 15-20 second.

Hope this information is of any use, am trying to get hold of Jaguar dealers to fix this issue. If you come accross any solution please do let me know too

usually after opening the door you can deactivate the alarm by pushing th unlock button or simply insert keyy in ignition and turn it on.

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.

SOURCE: can not lock car by key remote . toyota rav 4 53 plate

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.
