Lost car keys, how to replace ignition/door locks

Probably can't be done if it is late enough to be fitted with a security system. In that case the key will have a coded transponder which the system will recognise and send a signal the the engine management to switch it on.

You either need a correctly coded key or remove the engine ECU and have it decoded.

Try using your key in drivers and passengers door to lock and unlock it. That works on some vehicles to reset/disarm, security/anti-theft systems. Otherwise you may have to check owners manual or call Ford dealer service dept for quick instructions.

You can probably go to a junkyard, and steal the tumbler out of another cars ignition, just make sure that you have the set of keys to go with it. As well, if your ignition key is for your locks as well, make sure that you take those tumblers out of the door because you'll need those as well.

There should be 8 cuts total on the key. While the door and the ignition share some of the same cuts you cannot get all the cuts from one cylinder. I believe that the door cylinder only uses 6 cuts and the ignition cylinder uses 7 cuts. The cut closest to the head of the key is #1 and the cut closest to the tip is #8. If I remember correctly the ignition cylinder uses cuts 1 - 7 and the door cylinder uses cuts 3 - 8.If the locksmith cannot decode the ignition cylinder you can try to contact you local ford dealer and see if they can find a key code and cut a key from that otherwise you may have to replace your ignition cylinder.

These are the items in the starting system to check out:
Ignition switch, Battery cables( even the one off the starter ) neutral safety switch , starter relay. Make sure the battery you have is the correct one for your vehicle. Use owners manual it will tell you cold cranking amps (CCA) your vehicle requires.
I would focus on battery, cables and ignition switch it that order.

Many Ford trucks, vans and suvs use PATs (passive anti-theft) keys. These keys prevent someone from copying your key to a blank and using the blank. There is a small chip in the key which the vehicle must recognize before it will start.
PATS is Ford Motor Company's passive anti theft system. In 1996 it started showing up on select models of Ford and Lincoln Mercury vehicles. The keys for these vehicles have a tiny radio frequency transponder imbedded in the plastic Head.
When you attempt to start the vehicle, the onboard computer sends out a RF signal that is picked up by the transponder in the key. The transponder then returns a unique RF signal to the vehicle's computer, giving it the ok for the vehicle to start and continue to run. This all happens in less than a second, and is completely transparent to the vehicle operator. It is a very effective system that does its job without the vehicle owner having to think about it, or modify his / her usual routine.
The PATs key is used on the following Ford family trucks and SUVS:
1998-up F-150
1998-up Expedition
2000-up Excursion
1998-up Explorer
1998-up Ranger
1998-up Lincoln Navigator
1998-up Mercury Mountaineer


Additionally, PATs can be found on the follow Ford family cars and mini-vans:
1998-up Contour
1997-up Crown Victoria
1999-up Escort
2000-up Focus
1996-up Mustang and Taurus
1998-up Windstar
1998-up 2000-up Lincoln LS
1998-up Lincoln Mark VIII, Lincoln Continental and Lincoln Town Car
1997-up Mercury Grand Marquis
1998-up Mercury Mystique
1996-up Mercury Sable
Following are the instructions for programming a blank key (you must have at least one working key for this procedure).
The PAT
1. Make sure you have both keys.
2. Turn on car but don't start. Watch "theft" indicator untils it goes out.
3. Turn off and repeat procedure with second key.
4. After "theft light goes out, insert new key and turn on.
5. Wait until the theft indicator goes off and then turn off switch.
6. Wait thirty seconds. New key is now programmed into security module. Repeat for any other keys.


1. Erase any old codes by entering the factory code.(buttons will light up)
2. Press 1/2 button within 5 seconds.
3. Press 7/8 and 9/0 buttons at the same time within 5 seconds.

To set new code:

1. Enter factory code (numbers will light up)
2. Press 1/2 button within 5 seconds.
3. Enter personal 5 digit code(decide beforehand) within 5 seconds of each previous one.
To unlock all the doors,press the 3/4 button within 5 seconds of the driver door unlocking.
To lock all doors and set alarm system,press 7/8 and 9/0 at the same time.
To disarm or reset a triggered alarm,just enter personal or factory code.

Do not set a code with five of the same consecutive numbers. It's too easy for thieves to figure out.

Deactivating and Activating Autolock

To deactivate the "autolock":
With all doors and tailgate closed but NOT locked,and ignition OFF.
1. Enter 5 digit code
2. While holding 7/8 button in, press and release the 3/4 button.
3. Release 7/8 button
The horn will chirp once if the "autolock" was deactivated
or two times if "autolock" was activated.

To reactivate the system,repeat steps 1 thru 3

Alternate Method To Deactivate And Activate Autolock

Do steps [1] through [5] (below) within 30 seconds or you'll have to do it over. If you have to do it over, wait 30 seconds between attempts.
Close all doors securely.

1.Turn the ignition key to ON.

2.Press the power door UNLOCK control THREE times.

3.Turn the ignition key from ON to OFF.

4.Press the power door UNLOCK control THREE times.

5.Turn the ignition key back to ON .The doors should lock and unlock.

6.Press the power door UNLOCK control. The horn should chirp ONCE to confirm successful switching of the autolock system.


Hope this help you (remember comment and rates this).

You don't need to buy anything but a key. Just take your VIN # and proof of ownership to a Ford dealer, and they can cut you a new key, as can a good locksmith.

Go to any Ford dealership with your VIN #, and proof of ownership, and they can cut you a key. A good locksmith can do the same.

for 98 contour issue. TSB 98-21-14 not covered by warranty

This TSB article is being republished in its entirety to include the 1999 Cougar . ISSUE: The ignition key may be difficult to insert or remove and/or key chimes may sound with the ignition key removed and driver's door open on some vehicles. This may be caused by internal design characteristics in the ignition lock cylinder increasing insertion/removal efforts which may allow the lock cylinder to stick.
ACTION: Install a revised ignition lock cylinder. The revised ignition lock cylinder should reduce the possibility of high insertion/removal efforts and ensure proper chime function. Refer to the following Service Procedure for details.
SERVICE PROCEDURE

1. Verify customer concern.
2. Observe the ignition lock cylinder as the key is removed. If the lock cylinder snaps outward to the non-depressed position and the chimes stop sounding, continue to Step 3. If it does not snap outward, replace the ignition lock cylinder with the appropriate cylinder by referring to the Parts Block in this article.
3. Insert and remove the ignition key from the lock cylinder. If binding or high efforts are encountered, replace the ignition lock cylinder.
4. From the Parts Block, select a lock cylinder with a part number suffix identical to the center character of the key code of the vehicle. The suffix must match the center key code character to maintain a single key system.
5. Install the replacement lock cylinder, by referring to the 1998 Contour/Mystique Workshop Manual, Section 211-05 or the 1999 Cougar Workshop Manual, Section 211-04. NOTE: KEYS INCLUDED WITH NEW IGNITION LOCK CYLINDERS ARE CUT FOR THE IGNITION ONLY. IN ORDER FOR THE KEYS TO FUNCTION IN THE DOOR LOCKS, THE KEYS MUST BE CUT TO THE DOOR CODE OF THE ORIGINAL LOCKSET.
