Question 1

What is the cheapest way to replace a lost key for a 2002 Chrysler Sebring?

Accepted Answer

Call a mobile locksmith first. Dealers on these older Chryslers will still charge you for the key blank, programming labor, and often a diagnostic fee stacked on top, and they want the car towed in on their schedule. A mobile locksmith comes to you, works from the car, and handles the whole job in one visit. With EZ Car Keyz you get the key cut and programmed on site, no tow, no appointment, no itemized surprise at the end. Call for current pricing and I can give you a straight number in about two minutes.

Question 2

How much more does all-keys-lost cost compared to just getting a spare made?

Accepted Answer

It costs more, and the gap is real. When you have a working key, adding a spare on a 2002 Sebring is a shorter job. The immobilizer already has a valid key registered, so enrollment is faster.

All-keys-lost is a different situation. The module PIN has to be extracted first, then the memory gets wiped, and then the new key gets registered from scratch. That sequence takes more time and requires the right equipment to pull the PIN without a working key present.

Bottom line: get a spare made while you still have one working key. It will save you money and it will save you from a situation where you are stranded.

Question 3

Do aftermarket transponder keys work on a 2002 Chrysler Sebring, or should I stick with OEM?

Accepted Answer

Aftermarket keys work on these when the transponder chip inside is the correct type and the key is from a reputable supplier. The problem with cheap shells off Amazon or eBay is that quality control is inconsistent. Some will program fine. Some will not take programming at all, and you will not know which you have until someone tries.

The blade cut and the chip both have to be right. A key that looks correct but has the wrong chip inside will never start the car no matter how many times you run the relearn.

I carry verified compatible blanks for the 2002 Sebring specifically. If you bring your own key blank and it fails, you are still paying for the labor. It is a better bet to let me supply the blank and know it is going to work before I start the job.

Question 4

My 2002 Sebring starts and then the security light stays on solid. Is that a problem with the key or the immobilizer?

Accepted Answer

On the 2002 Sebring, the security light behavior tells you a lot. If the light comes on and then goes off after a few seconds once the car is running, that is normal operation. The system is doing its check and clearing.

If the light stays on solid while the car is running, that usually means the immobilizer module read the transponder chip but logged something it did not like, or there is a communication issue between the module and the ignition system. The car might run, but the system is flagging something.

If the light flashes rapidly and the car will not crank at all, the module did not recognize the key. That could be a worn or damaged key, a failing transponder chip inside the key, or a module that needs attention. A scan can pull the stored fault and tell you where the problem actually lives before anyone starts replacing parts.

Question 5

Can I program a second key for my 2002 Sebring myself at home, or do I need a tool?

Accepted Answer

You need a tool. There is no onboard DIY relearn sequence on the 2002 Sebring for transponder keys the way some older vehicles had. The immobilizer module requires PIN-based programming, which means a programmer that can communicate with the module through the OBD port and either read or input the correct PIN. Without that, a correctly cut key blade will turn the ignition but the car will not start because the module will not recognize the chip. Buying a pre-cut key online and expecting to self-program it will not work on this car.
