I cant unlock my Ford XR6 i have already replaced key remote battery


Do not know where you live but some autoparts stores have a tester for the Key FOBs which let you know if the Fob is working. You might have bought a dead battery. If the Fob is working perhaps the battery in your vehicle is dead and that is why the locks do not work.

Usually there is a real key attached to a Fob. Just use the key.

Key remote won't lock the door change fuse and battery in remote still don't work


Common Reasons Why Your Car Door Isn't Locking Properly The key fob battery is dead: This is one of the most common reasons why your car door lock is not working. If your locks aren't working, replacing the battery in the key fob could solve the issue. The key fob is faulty: If the battery isn't the problem, the issue may be with the fob itself. If you go to your car dealer, they can hook the fob up to a computer and make sure that the programming is still good. If it's not sending a signal, the fob will likely have to be replaced. A fuse is blown: If one door doesn't work, but others do, the problem could be a blown fuse. Replacing the fuse will correct the problem. This is a cheap and easy fix The solenoid is bad: Again, if one door doesn't work, but others do, the problem could be with the door lock solenoid. Replacing it may require removing the car door panel You have a broken wire: If the lock isn't getting power, hold the lock switch either up or down, and then open and close the door repeatedly to see if the lock will work. If it works sometimes, you probably have a broken wire

Why would my Aerostart j5f-tx2000 remote key fob not transmitting


I would suspect it needs the power cell in the key fob replaced.
It may have enough electricity left to work the little LED indicator but not enough to transmit. If this is the fob you use most of the time it would make since that the battery would be depleted before the other just because of the higher use.

Replacing the battery cell in the fob is what I would try first.

Key fob will not reset after replacing battery for my 2001 volvo v70?


Just replacing the battery in a key fob should not require any reset! If the power door locks work using the remote or key then it could be the switch is faulty!

I cannot lock or unlock my car with my key fob


Test the battery inside key fob, should be at 3 volts, if is less than 3 volts replace the battery. If that does not work you may need to replace the key fob, on this vehicle you can program the key fob through the radio, the car manual shows you how to do this.

Before replacing the old key fob you can try to resinc the fob to the car by pressing the lock and unlock buttons at the same time for about 15 sec, if the door locks cycle the the fob will work again.

My 2006 cadillac sts key fob all of a sudden is not working it says no fob detected and i have the fob what can b wrong??


Some late model fobs contain electronics beyond the push buttons.
Batteries are replaceable...small screws may let you do this.
If the battery is not the cause....a replacement fob may be expensive. A road service technician can probably troubleshoot and replace cheaper than dealer !

Need to reset the key fob after replacing the battery


You should not have to reset the key fob after a battery replacement. The signal from the key fob stays the same and is programed to the reciever.
If the key fob needs to be reprogrammed then follow these steps.
1. Have all key fobs with you during programming.
2. Sit in the vehicle with all doors closed.
3. Lock all doors using the Lock/Unlock switch on the door.
4. Insert and withdraw the ignition key 7 to 9 times within 10 seconds (do not turn the key, just insert and withdraw).
5. The 4 way flasher indicator on the dash should flash once or twice.
6. Insert the ignition key and turn it on (key on, engine off).
7. Press any button on one remote and the 4 way flasher indicator on the dash should flash once.
8. If you have more key fobs to program use the Lock/Unlock button on the door to unlock the doors and then lock the doors.
9. Press any button on the next key fob and the 4 way flasher indicator on the dash should flash once.
10. Repeat if you have more key fobs. Only 5 can be programmed.
11. To exit, simply turn of the igniton and remove the ignition key.
12. Unlock the doors using the Lock/Unlock switch on the door and exit the vehicle.
13. Make sure the window is down when testing remotes in case you leave the keys inside.
14. Close all doors and test all remotes that were programmed.

Do not skip any steps or the process will not work.

If the 4 way flasher indicator does not work when inserting the key, you will need to start the process from the begining. If it still does not work the receiver may be your problem.

If the 4 way flasher indicator does not flash when pressing any button on the key fob then the key fob is the problem (dead battery or defective remote)
