Jaguar flip key batteries can be tricky to replace, below is a detailed diagram with instructions for replacement. The text is also quoted below.

“Key transmitter battery renewal

When the battery needs renewal there will be a significant decrease in the effective range of the key transmitter. To renew the battery, follow the procedure below.

• Using a small, flat-blade screwdriver, separate and pull the transmitter (A) from the key body.

• Insert the screwdriver into the groove between the covers (B) and, by twisting the screwdriver, prise the covers apart.

• Unscrew and remove the small screw (C) and remove the printed circuit board, taking care not to touch the battery terminals. Remove the battery and dispose of it safely.

• Fit a new cell, type CR2032 (available from your Jaguar Dealer), with the side marked with the positive symbol (+) downwards in the battery receptacle. Avoid touching the new battery as moisture/oil from the fingers can reduce the life of the battery and corrode the contacts.

• Replace the printed circuit board making sure to engage the board under the securing tabs (D), and secure with the screw.

• Refit the cover and click into place with thumb pressure.

• Slide the transmitter back onto the key body.“

Most newer Fords equipped with keyless entry are also coming with more advanced features such as smart locks, autolock, autounlock and the power door lock inhibit feature. Sounds great you say but what does all of that mean? In this post I will attempt to give an explanation for these features and at the end, list the various procedures for enabling/disabling them.

Ford Smart Lock Feature

The smart lock feature basically helps to keep you from locking your keys in the ignition. If you try to lock the doors using the power door lock button with the key still in the ignition and one of the doors open, it will lock and automatically unlock the doors to remind you that you left the key in the ignition. You can still lock the vehicle but you have to use another key in the door, the key fob or use the manual lock control on the door. If both doors are closed the vehicle can be locked using any method, even with the key in the ignition.

Ford AutoLock/AutoUnlock Feature

The autolock feature will automatically lock your doors when all of the doors are closed, the ignition is in the run position and the vehicle is traveling faster than twleve miles per hour. Autounlock is just the opposite in that it will unlock your doors after the vehicle comes to a stop, the ignition is turned off and the drivers door is opened. These features are only available with vehicles coming equipped with an automatic transmission.

Ford Power Door Lock Inhibit Feature

The power door lock inhibit feature will disable the power door locks (and trunk release) after the ignition is turned off and the vehicle is locked, using either the key fob or the drivers door (after it is opened and closed). The power door locks are then reenabled when the vehicle is unlocked using the key fob, any door is opened from the inside, or the ignition is turned on. I’m not real sure as to the usefulness of this feature but it can be disabled/enabled with an on board procedure.

Enabling/Disabling the Power Door Lock Inhibit Feature

1. Insert the key into the ignition, turn it to the RUN position. (do not start the vehicle)

2. Press the UNLOCK button three times using the drivers side door lock panel.

3. Turn the ignition to the OFF position.

4. Press the UNLOCK button three times using the drivers side door lock panel.

5. Turn the ignition to the RUN position, the horn should chirp to indicate program mode.

6. Press the LOCK button two times using the drivers side door lock panel. The horn will chirp on time signaling the the feature is turned off. If the feature is turned on the horn with chirp one time and honk one time.

7. To exit program mode, turn the ignition OFF.

Enabling/Disabling the AutoLock Feature

1. Insert the key into the ignition, turn it to the RUN position. (do not start the vehicle)

2. Press the UNLOCK button three times using the drivers side door lock panel.

3. Turn the ignition to the OFF position.

4. Press the UNLOCK button three times using the drivers side door lock panel.

5. Turn the ignition to the RUN position, the horn should chirp to indicate program mode.

6. Press UNLOCK, LOCK using the drivers side power door lock panel. The horn will chirp once if autolock is disabled or twice if it was enabled.

7. Turn the ignition OFF, the horn will chirp once to signal the procedure is complete.

Enabling/Disabling the AutoUnlock Feature

1. Insert the key into the ignition, turn it to the RUN position. (do not start the vehicle)

2. Press the UNLOCK button three times using the drivers side door lock panel.

3. Turn the ignition to the OFF position.

4. Press the UNLOCK button three times using the drivers side door lock panel.

5. Turn the ignition to the RUN position, the horn should chirp to indicate program mode.

6. Press LOCK, UNLOCK using the drivers side power door lock panel. The horn will chirp once if autounlock is disabled or twice if it was enabled.

7. Turn the ignition OFF, the horn will chirp once to signal the procedure is complete.

As always, check with your owners manual or local dealer to verify if your vehicle is equipped with these features.

Most people don’t realize that Ford, Mazda and GM transponder keys can be programmed without a scan tool or a trip to the dealer. With Fords and Mazdas you will need to have two keys that are already programmed, GM’s require one key to be already programmed.

The procedure for Mazdas and Fords is as follows:

Insert the first programmed key into the ignition and turn it to the RUN position (do not start the engine), wait for the security light to go out, remove key.

Insert the second programmed key into the ignition and turn it to the RUN position (do not start the engine), wait for the security light to go out, remove key.

Insert the NEW key into the ignition, turn it to RUN (engine off), wait for the security light to go out.

The key is now Programmed.

The procedure for GM vehicles is similar except you only need to cycle the ignition once with the first key, take it out and insert the new key, turn the ignition to RUN (engine off). When the light goes out the key is programmed. This should work for all GMC, Pontiac, Cadillac, Chevrolet, Buick, Saturn and Hummer vehicles. This should be a time saver for people who would like to purchase these chip keys online.

To have these keys cut, any local Locksmith in your area should be able to do it for you at a very minimal charge.

As a Locksmith, one of the most common failures of keyless remotes that I would come across is a broken housing. Over time, the stress from keeping your keys in your pocket or purse can weaken the plastic and eventually break it. Most commonly the key ring loop is the first to give. Remote head keys face a similar problem but they can also break where the key attaches to the remote, Lexus keys are notorious for this.

So what are you supposed to do with a broken remote key or remote housing? Luckily the housing or “shell” can usually be replaced at a substantial savings over replacing the remote itself. They are very easy swap out, it usually just involves unsnapping the old case and swapping over the transmitter into the new housing. You can shop for remote housings right here at CheapFobs.com, check out our homepage and enter your vehicle into the search bar plus “shell”. ie: Lexus Shell or Dodge Shell .

Not every vehicle will be listed but it’s worth it to search before having to replace the entire remote, especially in the case of the Lexus where the key shell is around 10 dollars and the cost to replace the entire key can be over 200 dollars!

Why yes they are. I’m talking about Durango’s from 2004 - 2007, possibly 08’s too. The problem with these remote head keys is the battery terminal clip can very easily break away from the circuit board. It is unknown to me whether this is a problem with weak solder, cheap materials, or poor quality control but what is known is that thousands of people have experienced a premature failure of the these fobs.

It is amazing that Dodge has released and continues to release such a defective product onto the unsuspecting public and will not honor the key under the factory warranty. The cost to replace it at the dealer is around 150 to 200 dollars! If you own a Durango or any Dodge / Chrysler / Jeep vehicle with a remote head key that is in good working order I would recommend taking extreme care to protect it. These keys can fail by dropping them or even looking at them funny.

If you have a key that has already failed, you do have a couple of options available to you. The first and obvious would be to bite the bullet and replace it. The second option would be to attempt to repair it yourself. If you have any sort of experience repairing electronics this would be an easy job, just resolder the terminal back onto the circuit board. If the thought of that sounds scary to you, as a last resort , you can open up the housing and reposition the terminal clip over the board, holding the battery in place.

Take a piece of electrical tape and tightly wrap it around the lower half of the housing several times. Snap the housing back together and screw it down. (will be tight) Take a knife or razor blade and trim the excess tape from the housing. (it will now be wrapped entirely around the bottom piece) If it worked, you should have a working remote. I would only do this as a temporary fix and would not really recommend it for a permanent solution.

If you would rather not bother with repairing it yourself you can purchase Durango Remote Head Keys right here for a fraction of the dealer price. These keys can be programmed with an on board procedure if you have 2 working keys present, working as in the key will start the vehicle. (not referring to the remote)

If you only have one working key (or none) a dealer or locksmith will need to program the key.
