How Concorde Keys Changed Over the Years
1st Generation (LH Platform)
Chrysler kept things simple here with a plain mechanical key. No transponder chip, no immobilizer, no electronics to worry about. We cut it on-site in minutes and you are on your way.
2nd Generation (LH Platform)
Chrysler stepped things up here with the Sentry Key Immobilizer System, or SKIM. Your key now carries a Texas Crypto 4D/4D64 transponder chip inside the head, and the car will not start unless it recognizes that chip. The 3-button remote runs on a CR2032 battery, and programming goes through the OBD-II port under your dash.
3rd Generation (LR Platform)
Chrysler moved to the LR platform but kept the Texas Crypto 4D/4D64 transponder chip. You still get a 3-button remote head key with a CR2032 battery, but the SKIM module communicates differently. We pull the PIN code through the OBD-II port using Autel or SmartPro and program the new key right in your driveway.
Which Key Does Your Concorde Use?
A straightforward metal key with no chip inside. If you have a separate remote fob, that is a standalone unit with its own battery.
Your key has a Texas Crypto 4D/4D64 chip embedded in the plastic head. The car checks that chip every time you turn the ignition. Three buttons handle lock, unlock, and trunk.
Similar look to the 1998-2001 key, but this one still carries the Texas Crypto 4D/4D64 chip. The remote and transponder are built into one unit with three buttons.
What to Expect Price-Wise
Every price includes the key blank, cutting, transponder programming, remote pairing, and on-site testing at your location.

Over 1,000 five-star reviews say more than any comparison chart, but here are the numbers anyway.
Common Concorde Key Problems
SKIM Module Failure
The Sentry Key (SKIM) Module under your dash is the top reason a 1998-2004 Concorde refuses to start. When it fails, the car cannot verify your transponder, killing fuel and ignition. We diagnose via OBD-II and program on-site.
Transponder Key Recognition Loss
Turn the key, nothing, security light blinks. Usually hits after a battery disconnect or jump because SKIM lost sync. We see this in Simi Valley and Oxnard summers. A quick OBD-II relearn gets your existing keys working again.
Worn Ignition Cylinder
People think they need a new key when the real problem is a worn ignition cylinder. High-mileage Concordes develop tumbler wear; key sticks, turns hard, or will not reach start. We check the cylinder first; sometimes replacement is the fix.
Remote Fob Battery Drain
First check: the battery. Your 1998-2004 Concorde remote uses a CR2032; when it drains, lock, unlock, and trunk quit. Catch: some fobs develop internal shorts that kill fresh cells in days. If a new CR2032 dies fast, the fob needs replacing.
Can You Program a Concorde Key Yourself?
No programming required. This is a plain mechanical key with no transponder. Just get it cut and you are good to go.
You can program the keyless entry remote yourself using a lock/unlock/panic button sequence in the ignition. But the transponder chip requires a professional scan tool. Remote buttons, yes. Starting the car with a new key, no.
Same deal as the second gen. The remote pairing procedure works at home, but programming the ID46 transponder chip to the SKIM module requires professional equipment and a PIN code. You cannot DIY the transponder part.

Did You Know?
The 2002-2004 Chrysler Concorde adopted the shorter LHS body, trimming 1.4 inches from the overall length compared to the previous generation. Chrysler also bumped the Limited trim's 3.5L V6 up to 250 horsepower. It was a subtle but meaningful refresh that gave the Concorde a tighter, more athletic stance without changing the cabin space.
