Hi, I got a 2007 Focus used and it only came with one key, and no keyless fobs. It is the one on the right. The one on the left is from my '02 F150. I can see the chip on the F150 key, but I see nothing on the Focus key like that.

It this simply a blank, old school key and the PATS system has been bypassed? Or was the design changed and it still has a chip molded into the plastic? I'm wanting to get some keyless fobs programmed and am wondering where this key puts me for a starting point of that process.

Thanks,
Matt

That key (on the right) does not appear to have a chip. There is no way to 'bypass' the PATS. It is possible that the lock cylinder was replaced and to keep from having to have new keys programmed the PO simply hid the old key near the PATS transceiver.

Thank you for the response, Paul, I appreciate it.

So for me- the mystery deepens. There is a key/chip buried in the steering column? I'm tired of using the same key to unlock the vehicle and start it. It would be less bad if there were a lock cylinder on the passenger side. This key is getting to have a lot of miles on it doing double duty of unlocking the door and being used in the ignition.

I'm just afraid of rounding the edges too much and it not properly actuating the tumblers in the cylinders. I remember the old Ford days of the oval and square key heads- one for the door locks, the other for the ignition.

Can the generic remote entry fobs available on Amazon be programmed to recognize the chip that the pats system is currently seeing? I know there are a hundred threads on key programming on the site, but I haven't come across one with just a single generic, non-transponder key, so I'm a bit lost or haven't been able to spot it.

I do appreciate any input or link to a thread I haven't been able to find.

Thanks again.

I can only speculate that is what is going on since you seem to be able to start the car with a 'non-chip' key'. There is no other way the 'bypass' the PATS.

Im not sure I understand what you are asking. The remote door lock/unlock using the fob has nothing to do with PATS which is an starter/ignition disable system based in the PCM. The remote door lock/unlock system works via a receiver in the GEM module. I believe you should able to purchase a remote fob for your year/model and simply program it to the GEM so that you can remotely lock/unlock the doors if your Focus was equipped with this feature (almost all 05-07 Focus which had power door locks did).

To program the remote entry transmitters:
1. Close all doors and fasten the driver’s seat belt to ensure conflicting chimes do not sound during the procedure
2. Put the key in the ignition.
3. Turn the key from the 2 (OFF) position to the 3 (ON) position.
4. Cycle four times rapidly (within six seconds) between the 2 (OFF)
and the 3 (ON) position. Note: The fourth turn must end in the 2 (OFF)
position.
5. Within 20 seconds press any button on the remote entry transmitter.
Note: If more than 20 seconds have passed you will need to start the
procedure over again.
6. Repeat Step 5 to program each additional remote entry transmitter.
7. Turn the ignition to the 3 (ON) position after you have finished
programming all remote entry transmitters to exit programming mode

Good luck
Paul

 

It's a PATS Key, The chip is molded inside and non removable like the your F-150 Key. Ford used different style keys depending on the year, make and model that was sold, however some keys are interchangeable with other Models.

 

Thank you for the response, SkyPilot.

 

X2 on the molded in permanently key idea, Japanese cars have done it for years. Key plastic gets molded over chip and cooled so fast it doesn't hurt the chip. To know, take key and get a $3 non-chipped 'valet' key copy made of it and try to start the car with it, most likely it will not start if the chipped one is nowhere near the ignition cylinder.

 

It is a chip key. They get used a lot when people don't want to spend 150.00 compared to 40.00.

Just as an FYI/TIL:

The old two-key system was for valet service. The square key unlocked the doors and fit the ignition. The round key opened the trunk and unlocked the glove compartment. This allowed vehicle owners to secure valuables in the trunk or glove compartment and not worry that the valet (or teenager, or brother-in-law, etc.) was stealing their Aviators or their Smith & Wesson or the new ad campaign designs for WHAM! (If you ain't eatin' WHAM!, you ain't eatin' ham!) With the decline of valet services the two key system became unnecessary in mass-market vehicles. Some high end manufacturers still use the two key valet system.

 

Thanks for the responses. Anyone know if a non-transponder key would unlock the door & hatch? Or is a signal from a transponder key needed to unlock the door/hatch outside the car at the lock?

I got the keyless fobs programmed, that was super easy!

 

The doors and trunk/hatch locks have nothing to do with the transponder. It is only used for the PATS system.

They should open with it.
