Question about 1999 Mercury Cougar

Open Question

99 merc cougar ignition locked up, need new tumblers

I have a 99 merc. cougar that the ignition won't turn once the key is in. The Key has many scratch marks and some of the grooves are bent over. A few people I have asked said its very possible the tumblers are busted and/or the key is too mangled to open the tumblers and turn.

I have the steering column open and have removed all the visible and attached parts to the ignition switch, but can't seem to remove the cylinder. Is there some hidden release or trick to removing the ignition switch so I can try a new tumbler/key set?

Also I have been told that my key has a radio chip so I can't use just any key but when I purchase a new key & tumbler set I can take it into a shop and have them sync it to my car somehow, is this something only the dealership can do or any basic repair shop?

    We had a new key made that worked for a while but now it will not turn at all. I also can not get the ignition key out to replace it.

    Yeah, same here on getting it out, I'm going to end up paying a lock smith to drill it out (must be in the run position to remove but can't move key) then replace it...ug

SOURCE: open broken trunk

There are 2 possibilities. 1. Persuade it from the outside. Depending on the damage you might be able to just stick a large screwdriver in to the tumbler and turn it clockwise. OR if the rest of the lock and tumbler can be removed without further damage to the metal around it then remove it. You can then shine a flash light in and see a small rectangle where the lock rod used to go in to. Use a screw driver to unlock the trunk by inserting it in to the rectangle and turning clockwise. 2. Remove the back seat. If you can't remove the rest of the lock cylinder, then you'll have to remove the back seat, crawl through the trunk and use a pair of pliers to grab and twist the lock rod that goes through the trunk lock. To remove the rear set you first push backwards and lift up on the bottom seat frame. You'll need to apply force to the lowest point possible on the frame. Tt is easiest to do one side at a time. Sometimes if you look under the seat you can see where the seat frame hooks in to the body of the car. Once the lower seat cusion is out you'll need to unbolt the lower corners of the seat. I believe on this car the bolts that hold the lower part of the upper seat cushion also hold in the seat belts. Seat Belt bolts require a large TORX bit. You might also need an impact wrench to get the seatbelt bolts out. I have seen people rip the seat back away from the bolts as it is only paperboard between the seat and bolt. Keep in mind though if you do this you will not be able to properly reinstall the seat and that could be hazardous in a sudden stop or accident. Once the seat back is unbolted it lifts off of a couple of hooks on the body. Then you'll need to remove some insulating materials and finally you can crawl in to the trunk.

SOURCE: ignition tumbler key

Place key into ignition, use a paper clip and press the tiny hole on the switch. Turn the key back towards ACC position and pull the cylinder right out. Reverse procedure to install.

Try turning the steering wheel with your left handle(to get pressure off of the lock) while trying to turn the key with your right hand.

How replace a lock tumbler on a 1995 Mercedes benz c220


If the key does not turn at all in the ignition tumbler then your going to need to drill a hole in the side of the steering lock in order to manually release the steering lock and remove it complete with the ignition tumbler attached. If you get a new steering lock you can examine it to see exactly where to drill the hole and how to manually release it. If the key does turn at least to position 1 then all you need is the removal pins that slide into the small holes around the face of the tumbler. If there are no holes then once the key is in position 1 all you have to do is turn the tumbler housing to the left until is unscrews. Let me know if you need any further assistance on the removal if the key is stuck.

Key in ignition won,t turn 2004 ford escape


several things, does key go in and out easily, turn steering wheel in both directions while turning key. sometimes the steering wheel lock binds the lock cylinder and turning wheel releases the pressure and it will turn. other than that the ignition cylinder is jammed, wet key lightly with lubricant such as wd-40 and a light bit in key hole and try key again, If key is heavily worn out , try a different ignition key as it might not be disengaging all the tumblers in lock, if all this fails you need a new cylinder.

The car will turn over but won`t start but if I turn the key on and jump the starter it starts


Sounds like the ignition switch has gone kaput. The ignition switch come in two pieces, an electrical switch and a mechanical switch.

The switch electrical portion can be replaced separatly from the mechanical portion (tumbler that the key engages). It is not a real difficult repair but requires some mechanical knowlege of how the column is assembled.

This can be verified with electrical test equipment prior to buying a new electrical switch.

I would replace the ignition cylinder. the tumbler are wearing funny and this is causing the key to not turn or get stuck . I believe you have a pass key system on your car too . so after the cylinder is replace or rebuild you may need to do a relearn with the new lock cylinder. Not sure if you can rebuild the key cylinder and if a lock smith would have the right tumbler codes . but i know for sure if you buy the lock cylinder from a dealership they can code the tumbler to match the original key

1986 Thunderbird Starting problem, Turn key starts, let go of key stops


Replace the ignition tumbler--i.e. get a new ignition set with new key. This will require removing the plastic trim around the steering column and removing the old ignition set. It's a good DIY project, but you should get a Haynes manual for 83-88 T-Bird/Cougar. Try going to a junk yard for the replacement part. Crown Vics, Cougars, Grand Marquis', Lincolns all have the same type of set for those years.
