Question 1

What is the cheapest way to handle all-keys-lost on my 2016 Chrysler 200?

Accepted Answer

Call a mobile locksmith first. Dealer quotes for an all-keys-lost job on the 2016 Chrysler 200 run steep, and that's before you factor in a tow if the car isn't driveable. The job requires PIN extraction from the immobilizer module, clearing all previously stored key data, programming fresh keys, and confirming the start. We do all of that on site in Rancho Bernardo, including the RB Town Center area, without you moving the car anywhere.

The dealer usually wants the car dropped off and may hold it overnight. A mobile locksmith comes to the car, does the work there, and you're driving before we leave. Way less than the dealer, no tow bill, no waiting.

Question 2

Can you delete lost or stolen keys from my Chrysler 200 so they can't start the car?

Accepted Answer

Yes. The all-keys-lost procedure wipes all previously enrolled key data from the immobilizer and registers only the keys that are physically present during the programming session. Any fob that got lost, stolen, or handed to someone you no longer trust gets automatically deauthorized. It will not start the car.

This is worth doing any time you're not sure who has a working copy. You don't need to wait until every key is gone to request it.

Question 3

Does my 2016 Chrysler 200 smart key have a hidden emergency blade inside it?

Accepted Answer

It does. There's a small release on the fob body, and sliding it out gives you a mechanical blade cut to your car. That blade fits the driver's door lock cylinder for manual entry if the fob battery is dead or the car isn't responding to the wireless signal.

Here's the part most owners don't know until they need it: once you're inside, you can still start the car with a completely dead fob battery. Hold the fob directly against the start button and press it normally with your foot on the brake. The start button can read the transponder in the fob at close contact range, so you don't need the wireless signal at all. The car starts. A lot of Chrysler 200 owners find out about this for the first time in a parking lot somewhere, which is not the ideal moment to learn it.

Question 4

My 2016 Chrysler 200 shows a key warning on the dash but the fob battery is new. What's going on?

Accepted Answer

A fresh battery rules out the obvious cause, but it doesn't always mean the fob is fine. A few things come up repeatedly on these cars in forums.

First, check how the battery is seated. The CR2032 needs to sit flush against both contacts. If it was pried out instead of popped, the contact clips can get slightly bent, and a new battery at an angle gives you the same weak signal as a dying one.

Second, the fob itself can develop internal failures unrelated to the battery. The circuit board inside is small and the antenna connection can loosen over time, especially on a key that gets daily use. If the battery and seating check out, the fob may need to be replaced and reprogrammed rather than just swapped.

Third, if the warning appears intermittently and the car starts fine on the second try, that's often the fob antenna or a marginal signal condition rather than a total failure. Worth getting the fob tested before assuming you need a full replacement.

Question 5

I bought a replacement fob online for my 2016 Chrysler 200. Can I program it myself?

Accepted Answer

No. The 2016 Chrysler 200 smart key has no onboard self-programming sequence. There's no ignition-turn trick, no button combination, no DIY method. Programming requires a diagnostic tool connected to the OBD port and the vehicle's PIN. Without that, the fob you bought online is just a plastic shell.

The good news is that an aftermarket fob purchased online can usually be programmed by a locksmith or dealer, so the part itself isn't wasted. You'll just need a tech with the right equipment to finish the job. Call us and we'll take care of it on site.
