If central locking is ok by key then must be the plug from the keyless entry box,also it can be the inside relay (box defect).If the central locking does not work by key ceck fuses.

If the key had gone faulty, the key code must be re programmed on the vehicle computer. This can be done only using a PIWIS tool, available at the dealer or at a qualified Porche garage.
Try also the following reset:
turn ignition on,
turn off.
remove the transponder from the column
push any button on the fob within 6 seconds.
This procedure will reset the key synchronizing again with the vehicle computer.

SOURCE: Jag S-Type -intermitent fault where the remote fob does not work

This does not sound like a fob fault - but a locking control module fault , either in the hardware or software of the unit. Get it checked at a Jaguar dealers. When unlocking using the key - as soon as the door is opened you should hear a chime sounding inside the car - this is a timer counting down to sounding the alarm. If you put your key in the ignition as soon as you open the door the alarm should not go off and the chime should stop. If it does not this again points to a fault in the locking controller.
hope this helps - good luck.

SOURCE: key fob lights up but doesn't work even with a new battery

I'm more familiar with Range Rovers and Saab's when it comes to key fobs but if you changed the battery you have to re-program the key fob. If you do not have an owner's manual that can take you through the steps you might want to try: push and hold the lock button on the key fob, put it in the driver's side door and turn to lock. With the button still depressed turn back to open, remove the key and release the button. If this doesn't work check any and all fuses associated with your system and last but not least you could take it to a dealer. Good luck!

Keyless entry remote wont progam


It will not unlock the door the first time you push the button. This only registers the key fob ID into the computer. When you press the button on the key fob, press it only once and wait for the hazzard lights to flash twice again. Then open the driver's door. The key fob will not become active until you open the driver's door.

If your hazzard lights do not flash after you press the button on the key fob, there is most likely a problem with the key fob. Either it is not the correct key fob for your vehicle, or the battery is not in correctly or the key fob is defective.

The only other advice I can give you is to have it programmed with a scan tool. This way, the scan tool can verify that the computer in your vehicle is receiving the signal from the key fob.

It can be done either way, but if the "no scanner" way does not work, the rest of the system should be checked for possible problems.

Crimestopper SP501 car alarm/remote starter will not respond. The 2 way one doesn't work, the sidekick does.


You need to program your crimestopper sp-501 key fobs, you need to program both the 2-way and the 1-way key fobs, during the same key fob program session. First find your valet button/switch, when you have found it, turn your ignition on and press the valet button four times, if you have a toggle type switch for a valet switch, toggle it up and down four times, when its in remote key fob program mode, it will honk your horn 4-times followed by 4-parking light flashes. Once your have done this press the lock button on the 2-way key fob, horn will honk and the 2-way will sing a little song to confirm programed, then press the lock button on the 1-way key fob the horn honk will be your confirm programed. turn ignition off this will exit you from program mode. then shut all doors and test key fobs for operation functions....hope this helps you out

Remote control has stopped working. Have tried changing the battery of the remote control but that did not work.


Does the red light on the remote light up when you push any of the button
if no, replace remote
if yes, then try repograming the remote to the car again.
-Have remotes' ready. if you have two then fob#1 and fob#2 (doesn't matter which one is #1 or #2)
-each step has to be done within 5 sec or it will not work, but don't do it super fast.
1.turn key just to the "on" position (not starting) and push "lock button " on fob#1 once and release
2.turn key off
3.turn key just to the "on" position (not starting)and push "lock button " on fob#1 once and release
4.turn key off
5.turn key just to the "on" position (not starting)and push "lock button " on fob#1 once and release
6turn key off
7.turn key just to the "on" position (not starting) and push "lock button " on fob#1 twice (if you only have one fob, then stop here and go to step 8)and push the "lock button" on fob#2 twice.
8.turn key off and remove key from ignition.
if you did it right, remotes' should work again.
good luck

Need to program remote keyless entry for 2003 nissan pulsar?


If it is a 2003 model year vehicle follow this procedure. If it doesn't work, you may have the wrong fob which happens all the time.

Sit in vehicle and close all doors.
COMPLETELY insert and remove ignition key more than six times within 10 seconds.
Hazard lights should flash twice.
Turn ignition to ACC position
Press and hold any button on the new key fob hazard lights will flash twice
For a second key fob using the master lock switch, lock and unlock the doors then hold down any button on the second remote until the hazard lamps flash twice.
Then you are done open the door to exit the programming mode.
If the lamps didn't flash when holding down the key fob make sure you have the right key fob, they are different for each car.
