SOURCE: key fob will not undo

If you don't have one that works for the vehicle now, you'll have to take it to your local dealer to have it programmed to the vehicle. Some will charge for this, some will do it at no charge.

If you do have a remote that is programmed and working for the vehicle, then the following steps will allow you to program another remote:

1. Enter vehicle and close all doors.

2. Put seatbelt on (or clip it into the buckle) to shut the warning buzzer off.

3. Put key in ignition, turn to run position but don't start it.

4. Press and hold the unlock button on the working key fob and hold for 4 seconds, then also press the panic button.

5. Release both buttons and you should hear a single chime to indicate it is in program mode. You have 30 seconds after the chime to program any additional remotes you want to program.

6. Press and release both the unlock and lock buttons simultaneously on the remote you are programming. You should hear another single chime.

7. Within 4 seconds after hearing the chime, press either lock or unlock button on remote that you are programming.

SOURCE: hi,immobiliser problem?battery went flat,,managed to

Hi it sounds like you have done everything you can do, it now looks like your going to need to get the immobilizer reset, this can be done at most garages but its best if you shop around to see the best price you can get as its not cheap.

have you tried locking the door with the key and then opening it with the key then try the car see if it will work.

failing that its going to need the imob re-programming so that it accepts your key fob, it may just be that you need the fob replacing as the chip inside could have failed they will be able to test all this for you.

let me know if you need further assistance, not that theirs much more i can do without being their with the equipment to test the immobilizer, hopefully it will just be the fob that needs replacing.

you could just try one last thing when you get in the car and put the key in the ignition try holding the fob as close as you can to the ignition barrel as this is where it picks the signal up from so try holding it close to their and see if that then lets you start the car

failing that its going to be a trip to the garage.

plz rate this solution as i have a whole page of unrated posts, thanks

2007 Lincoln MKZ won't start and diagnostic says security system disabled motor? What can I do? I bought new key fob as well.

Andrew this has nothing to do with PATS immobilizer ,this is for resetting the vehicles contents theft system.

If You need to reset the anti theft system in Your 2007 Lincoln MKZ it is a pretty easy to do it just takes a few minutes. You should be able to reset it without using any special tools as well. All You need to do is turn the vehicle from off to on 8 times quickly without starting it and then leave it in the on position. You will then watch the locks in the car automatically cycle to lock and unlock. After that press and hold any of the buttons on Your key fob for 20 seconds until You har a beep. After that You can turn the vehicle off then start it again. If You have multiple problems with Your anti-theft system there may be a body control module problem that needs to be addressed by Lincoln.

How to disarm the alarm 2000 Mitsubishi Montero Sport with out a fob or door key.

Question edited for clarity. The word 'faub' does not exist - 'fob'.

My 2006 Toyota Tundra SR5 will not go into program mode to program my keyless entry pads

The security system on Toyota products are added by the distributor in your region. Many of those security systems will not allow more than 4 key fobs to be programmed into them. Have you owned this vehicle since it was new? Have you tried to program more that 4 key fobs into it? Have you tried programming it more than 2 times? If you security system has had more than 4 key fobs programmed in then the only way to get it to reprogram is the replace the security unit with a new one. I found this out the hard way and had to replace mine in my 2000 tundra.

WONT START.SECURITY LIGHT FLASHES WHEN TRYYING TO START

Anti Theft System - inmobilizer is actovated. Need disarm to start engine. Have you another key and fob? Try lock/unlock cycle with new key + fob. Your key may be corrupted.

Try also just unlocking the car with the key (not the fob) as soon as you unlock the door put the key in the ignition immediately and see if the car starts.

If you have your radio code it may be worth trying a total reset (leave the car unlocked) disconnect the battery and leave for 20 mins. then reconnect.

Hope help with this.
