Question 1

How long does it take to get a replacement key for a 1998 Chrysler Concorde at the dealer?

Accepted Answer

The programming itself is not the slow part. Once a tech is connected and the key is in hand, enrollment takes a few minutes. The delay at a dealer comes from parts availability, service queue scheduling, and sometimes just getting a tech who works on older systems regularly. A 1998 Concorde is over 25 years old at this point, and not every dealer keeps blanks for it in stock. You may be looking at an order wait before they can even start.

A mobile visit cuts all of that out. I come to you, I bring the blank, I cut it and program it on site. No waiting on parts, no drop-off, no service queue.

Question 2

What exactly is a transponder key and how does it work on this car?

Accepted Answer

The key has a small chip sealed inside the plastic head. When you turn it in the ignition, an antenna ring around the cylinder reads that chip. If the code matches what the immobilizer expects, the car starts. If it doesn't match, or if the chip is missing entirely, the engine will crank and may briefly fire, then stall. You can't feel or see the chip from the outside. It looks like a regular ignition key. The programming step is what pairs that chip's code to your specific vehicle. Without it, the key is just a blade that turns the lock but won't run the engine.

Question 3

Why does the dealer process take so long on Chrysler key jobs?

Accepted Answer

Parts ordering and scheduling backlogs are usually the real culprits, not the programming step. Once a tech is connected and the blank is on hand, the actual enrollment is quick. The time loss comes before and after that moment: waiting for a blank to arrive, waiting for a service appointment, and occasionally dealing with a tech who doesn't work older Chrysler systems day-to-day. On a 1998 vehicle, some dealers will also want to verify the immobilizer is functioning correctly before they commit to a programming job, which can add diagnostic time to the ticket.

For a 25-year-old Concorde, a mobile locksmith who works these systems regularly is often faster and costs less. The programming equipment for this era doesn't require the same authentication layers that newer vehicles do, so the job is clean and self-contained on site.

Question 4

My 1998 Concorde cranks fine but stalls right after it starts. Could this be a key or immobilizer problem?

Accepted Answer

Yes, and it's one of the more common patterns on vehicles from this era with transponder systems. A crank-and-stall where the engine fires briefly then dies usually points to the immobilizer not recognizing the key's chip. Could be a key that was never programmed, a chip that's failed, or an antenna ring that's not reading properly. A worn or damaged chip inside an older key can also cause intermittent stalls after years of use. Worth ruling out before assuming it's a fuel or ignition issue. I can test the key's chip and the antenna read on site before cutting or programming anything.

Question 5

Can I program a second key for my 1998 Concorde myself at home?

Accepted Answer

There is an onboard add-a-key procedure available for this generation of Chrysler that some owners have used successfully. It involves a timed ignition sequence with an already-programmed key present. That said, the procedure is sensitive to timing, and it only works when you still have at least one functioning programmed key in hand. All-keys-lost is a different situation and needs programming equipment.

If you want it done right the first time without risking a lockout, a mobile visit is the easier call. I bring the blank, cut it, and enroll it on site.
