Yes, there is a battery in the key fob. You'll have to open it up and replace it. If you are unsure how take it to the dealer or autozone or other type parts store and they can help you and sell you the battery.

Key buttons will not operate locking system,i have changed battery but still no good.use master key,gets me into the car but alarm goes off and also when i attempt to drive it.


I have the same problem kinda. Lost my master key and sent my ecu off with a home made 2 button key to program immobiliser. This key works to start the engin and drive but I cannot get the key to program with the alarm and locking system. You can try the following steps as may work for you.

I can get my car into programming mode after step 1 but step 2 does not work for me. The locks do not go off at all, not once or twice. Battery in remote key is fine as LCD lights red.

Can anyone help please?

I have a 2000 nissan primera and when i open the door the hazard lights flash then stop when i start the engin is this ment to happen?


No, its not supposed to happen. It sounds like you have a fault with the alarm system. When you open the door, it thinks its being entered illegaly, but when you put the key in the ignition contact, it recognises that the key is correct and will allow you to start the engine. You should take it to the dealer to check for the fault. Has the battery been disconnected recently ? or has the battery been replaced in the remote handset ?
It may be that the system requires resetting. To reprogramme the handset, do this -
obtain all keys
switch ignition on and off 6 times within 10 seconds
after 2 seconds, indicators will flash twice
press and hold unlock button
press lock button 3 times
release unlock button
indicators will flash once
if required repeat button procedureto programme remaining key remote handsets
switch ignition on
indicators will flash twice
remove key from ignition switch
check operation of all programmed key remote handsets

That should do it, if not then as i said you would have to go to the dealer.
Hope that helps

Ignition alarm will not stop 97 ford f150


The key switch usually breaks or wears out and makes contact. It is on the lock cylinder. This would cause the chime to not come on, or stay on. Sounds like the switch is bad.

1997 F-150/250 Warning Chime, Key-In-Ignition The key-in-ignition chime warns that the key is still in the ignition when the driver's door is ajar. The key-in-ignition warning chime will sound when:
  • GEM: Driver door is ajar, the ignition switch is in the OFF/LOCK or ACC position and the keys are in the ignition.
  • CTM: Driver door is ajar, the ignition switch is in the OFF/LOCK, ACC or RUN position and the keys are in the ignition.
The key-in-ignition warning chime will stop sounding when:
  • Driver door is closed.
  • Key is removed from the ignition.
  • GEM: Ignition switch is switched to the RUN position.
The key-in-ignition warning chime inputs are:
  • Ignition switch RUN position (battery potential on both RUN and RUN/ACC inputs).
  • Ignition switch ACC position (battery potential on RUN/ACC input only).
  • Key-in-ignition switch (grounded with key-in-ignition, open circuit with key-out).
  • LH door ajar switch (open circuit with door closed, grounded with door ajar).
This is a pic for a 98, could not find one for 97 which may be the older style which is more prone to break.

Program a remote key for 03 A6


I have an A4 and did this to re-program my key:

1. used the key to start the car...then turned it off
2. put the key in the driver door (door closed)
3. pressed the lock button on the key fob once
4. turned the key to lock the door.

This is basically the steps in the owners manual, but the car must be started with the key first, and the key must be in the door lock before pressing the lock button.
