My wife lost her keys. I had to by another key and program it to the car. Now, she has found her keys and the remote does not work. Does it have to be reprogramed or do I have to get another one? If the old one has to be reprogramed, how do I do it?

1. open the glove box the users guide answers that.
2. if lost said guide, it is free from Lincoln or google it free.
3. the car came new with 3 working keys, lost all? ask wife?
4. all you can do with all keys lost (both) is call a locksmith that can do cars, and ask. 3rd key is valet
5. or call autorepair shops for a cure.
6. or the dealer, in some case only they can and #1 book says those exact words no kidding.

there it is. see pages "secure_lock"
1st google hit.

and page 119 (up to 8 keys total) so losing both keys hard failure.
to do your own programming it takes 2 good key

end, most websites (gee 1000s ) on topic say the same thing

you can't bypass computer set software. You can however reprogram the key transponder and receiver. If you have NO working key, you need the dealership.

My experience with frequently-used vehicle remotes (any make) is this:
1. When relatively new or in good condition, if remote stops working, the button battery inside is dead or too low.

2. If battery is new, & remote still doesn't work, a solder joint on the circuit board inside may have come loose or broken.(You can try re-soldering using a low-heat pencil iron & thin RESIN-core solder -- even if you're not great at it, what do you have to lose?)

3. It's rather unusual for even an older, well-used remote to simply lose its programming.If this is the problem, it may be cheaper to buy a new after-market remote (or pair of remotes) that you can program yourself (only works with some brands & years of vehicles, so READ THE INSTRUCTIONS ON THEIR WEBSITE BEFORE BUYING AN AFTER-MARKET REMOTE), instead of going to the dealer for a normally HIGH-priced programming job.

4. Used OEM remotes that match yours exactly (check the part # of your remote & the used one you're considering) can often be purchased from a local auto wrecker (now called "auto recycler") for cheap ($5 to $10 is common), but will need programming.I always go thru the many they have, looking for one that appears new or like-new.

5. IF YOU MUST GET PROGRAMMING FROM A DEALER, usually it's the SAME PRICE whether you have 1 remote or several remotes/keys programmed at the same time.Since dealer programming is pricey, I always have 3-4 remotes and/or chip-keys programmed at the same time.(My dear wife loses chip-keys & remotes from time-to-time, so I keep a few spares on-hand.I've found inexpensive after-market chip-key blanks at some key cutters and/or auto parts stores, altho they still require programming after the copy is cut from yours.)

CAUTION:Some OEM anti-theft systems require that ALL remotes & chip-keys be programmed/re-programmed at the same time, whether they're original, used or new.Determine this IN ADVANCE, so you know what you're faced with.The good news is that for those vehicle manufacturers, dealers normally don't charge more to program/re-program multiple remotes and/or chip-keys, if all are being done AT THE SAME TIME.

6. If all else fails & you MUST buy a new OEM remote (which will require programming), try 2 things -- First, see if the dealer will make you a package deal on buying the remote (or 2 remotes, or a remote & a chip-key) AND doing the programming for a lower combined price.Second, it may be cheaper to buy a new OEM remote from a dealer who's had one in stock for a long time & wants to blow it out (or buy from online OEM seller) & then pay the normal programming price.See the CAUTION above.

There are lots of options here, so hopefully something is useful to you.

find the relay, it will be a multi functional one, good luck

Not sure about Chevy's, but when my husband lost his keys for his Ford, he got a new key programmed, and when he found his "lost" key, it still worked. Try it. Don't think it will hurt it if it doesn't work, but check with a dealer.

You need to get an aftermarket coded key which can be cut by the serial number of the vehicle.
You need to be a locksmith to get the cut codes or know a locksmith.
Then you have to get the car to the dealer and have the key programmed using the Tech 2 scanner.

You can take the car to the dealer and have them give you a key, programmed and everything but it will cost around $300 for the 1st key.

I bought a 2001 Catera for $1,500.00 because it had no keys.

I used serial number to get key codes and cut the key; doors opened and seller retrieved her personal stuff.
I towed car to dealership and had the key programmed; $130 for 10 minutes work (min 1 hour shop charge).
I then programmed 3 more keys (using a key code reader) instead of letting the dealership rape me.

BTW, they (dealer) also want $350 for a programmed door remote; the stock remote!
Instead, I bought a remote starter unit (Bulldog) with 2 remote fobs for $100 and now my wife can start and find her car easily.

did the lock smith cut key with resister in in maybee not gotta go to dealer get one cut then put old key in start car then turn of remove key put new key in turn on till security light goes out then start car

IS THE BATTERY DEAD? HOW LONG HAS CAR BEEN LOCKED UP? IF THE VALET KEY WILL NO LONGER OPEN THE DOOR YOU HAVE LITTLE CHOICE BUT TO TOW IT TO DEALER TO HAVE KEY CUT & PROGRAMMED

go to the car dealer and tell them that you need to get a new key and remote for your car
