Locked out no, the keyfob has a button that you press with a key to turn in the ignition, if it had a lock on the outside of the car i could use it to unlock it but i cant ind the lock, i guess it must be hidden some where on the car

O.k... usually it's in one of 3 places... either the front or rear bumper... under the frame rails... or under the hood, now... it's just a tiny red button... question... who put the alarm in... why can't you just call that person... explain the situation to them... and let them tell you where they put it?????

Resync key fob on vauxhall astra after battery change

Hi there, put the key in the ignition and turn the key to position 2 (so the lights come on the dashboard and you will have to make sure all the doors are closed before doing it). Then just either hold down the lock or unlock button down on the keyfob until the key syncs with the central locking, the car might lock and unlock itself with the button pressed down. That should be it. Let me know if it works

Hi i have a nissan terrano 2 extreme, i changed the battery in the key fob and it hasnt worked since how do i re-code the key fob please.

do you have the owners manual? Usually you have to turn the key back and forth a series of times. I know Ford has to be 10 times back and forth in less than 30 seconds. Then you aim the fob at the reciever on the dash. The owners manual should tell you. Ill give you a general nissan recode, im not sure if it will work for your Nissan.
. Place your key in the ignition and switch from the LOCK position to the ON position 6 times within 10 seconds ending with the key in the LOCK position
If done correctly the indicators should flash 2 times
2. Press and hold the UNLOCK button (black on P11) on your keyfob and while keeping it pressed then push the LOCK button (Red on P11) 3 times then release the UNLOCK button.
If done correctly the indicators should flash 2 times
3. To reprogram a further key/keyfob remove the key and put your second key in the ignition (or hold your fob close to the ignition barrel) leaving it in the LOCK position and repeat step 2.
Once done turn your ignition on and then back off to exit the coding procedure.
Test your keyfob(s) work ok. (do not leave your key in the car while doing this procedure incase you need to manually open the door with the key)

The key fob sometimes does not lock or unlock car doors. i have had a new battery fitted.but still not working properly.

Most of the keyfobs have instrctions on the back, or on the inside cover on how to change the battery in the keyfob and then reactivate.
If you can't find the instructions, you can try the following.

From outside of the vehicle, with all of the doors closed, push the unlock button, then the lock button, then the unlock button, then the lock button.
If that doesn't work;
Those keys/key pads, are highly sensitive to interfearence from other remotes, such as other keys with chips, garage door openers, etc., try to make sure that no other electronic products are near your keyfob.

I hope this helps you.

2004 xtype jaguar key fob suddenly stopped working car locked and alarmed if i use key in the door will the alarm go off if so how do i stop it

Your key fob needs reprogramming, and yes the alarm will go off when you open the door, but you have enough time to put the key in the ignition which will prevent the alarm sounding. Car is usable until you get the fob sorted by locking and unlocking using the key.

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.
