2006 Cadillac STS four door, 6 cylinder, keyless entry will not start. Transmission gear is stuck in Park and will not move. Now the battery is dead because the dashboard lights go on and would not go out. I had it towed to my home driveway. ---

If you have to ask you should have had it towed to a shop instead of home. ---

The dead battery is likely the reason the engine won’t start, and the reason the shift lever wouldn’t come out of park. ---

If lever still won’t come out of P once battery is charged and known-good, problem could be with the brake safety interlock. Designed to not let you shift out of P unless brakes are applied first. One easy test: Do the rear brake lights turn on when you press the brake pedal? ---

Charge the battery and report back with what symptoms still remain. ---

And you have a V8, not a V6 if the car is an STS. No STS has a V6. Edit: My mistake, there was a V6 offered in the STS. Thanks @Cavell ---

2005 and newer had v6 option. Just like srx. Seville name is not used. They just call it sts. ---

Try using the release mechanism to shift the gear out of park. If that doesn’t work, you may need to take the vehicle to a mechanic for a more thorough diagnosis. how could the transmission being stuck in park cause it to not start, when the vehicle needs to be in park to start? > [@veretilnyk\_183862](#): > > Keyless entry issues: If you are unable to start the vehicle due to a problem with the keyless entry system, it could be due to a dead key fob battery or a malfunction in the keyless entry system itself. Try replacing the battery in the key fob how would dead key fob battery cause a no start? Is this a thing with keyless/push button ign switches?
