  Q: How to replace the key lock cylinder and ignition switch in a Chrysler 300?

  A: If the key is hard to turn, the issue may not be the ignition switch or Ignition Lock Cylinder, but could be due to a misaligned transmission shift cable or Brake Transmission Shift Interlock (BTSI) cable. To replace the Ignition Lock Cylinder, disconnect the battery, remove the ignition switch and instrument cluster bezel, insert the key and turn it to ON, depress the retaining pin and remove the cylinder. Ensure the key is in ON position and align the D-shaped lug with the socket before installing the new cylinder. To replace the ignition switch, disconnect the battery, disable the airbag, remove the knee bolster and reinforcement panel, disconnect the electrical connectors and BTSI cable, and remove the switch. The Sentry Key Remote Entry Module (SKREEM) recognizes the key's encrypted RF signal, unlocking the doors and allowing the engine to start. If the key or SKREEM is replaced, reprogramming is required at a dealership.
