Chrysler's Sentry Key Immobilizer Module was introduced in the late 1990s and used across models like the 300M, Sebring, Concorde, and PT Cruiser. The key contains a transponder chip that communicates with a ring antenna around the ignition cylinder. If the chip code does not match, the engine cranks but will not start.
Chrysler was one of the first manufacturers to adopt the "Fobik" format, which combines the remote buttons and the transponder into a single plastic unit with no traditional key blade. Instead of a metal key, the Fobik has an integrated emergency blade tucked inside the fob body. Models like the 300, Town & Country, and early Pacifica use this system.
The current Chrysler Pacifica and Chrysler 300 use a push-button smart key system. The driver carries the fob, the car detects it wirelessly, and the engine starts with a button press. No key blade touches the ignition.
We replace all Chrysler key types, from traditional transponder keys to Fobik units to proximity smart keys. If you have lost every key, we create one from scratch at your location.
Every Chrysler key from the late 1990s forward requires electronic programming. We carry the Stellantis-compatible diagnostic tools to pair new keys and fobs to your vehicle's SKIM or smart key module.
Chrysler Fobik and smart key batteries wear out over time. If your fob is unresponsive, we start with a battery swap and test from there. If the fob itself is damaged, we repair or replace it.
Locked out of your Chrysler? We use professional non-destructive entry tools to open the door without damaging the vehicle. Minivan sliding door lockouts are something we handle regularly.
Older Chryslers with a physical ignition cylinder can develop wear over time. The PT Cruiser and Sebring are especially prone to ignition issues. We repair or replace the cylinder and rekey if needed.
If you have one working key, we can make a copy on the spot. This applies to transponder keys, Fobik units, and smart keys.
Current lineup: Chrysler 300, Chrysler Pacifica, Chrysler Pacifica Hybrid Recent and discontinued: Town & Country, 200, PT Cruiser, Sebring, Crossfire, Concorde, LHS, 300M, Aspen, Voyager
Kids climb in through the sliding door, the fob stays in a purse on the front seat, and the doors lock automatically. We handle this regularly and can get you back in quickly without any damage.
Even though both are current Chrysler models, their fobs are not interchangeable. When you call, give us the exact model and year so we bring the right equipment.
If your Town & Country Fobik is only working intermittently or requires you to hold it very close to the dash slot, the battery is likely the issue. We swap them out in minutes, and we always test the fob after the battery change to make sure it is communicating properly.
