Care won't shift out of park

If you battery is dead it will not work make and model would help

Press brake pedal and see if brake lights are on. The brake light switch is part of the parking release unit.

Lets start by checking your brake light switch.
Your car has a switch on the brake pedal that not only makes the brake lights come on, but also tells the transmission it can shift out of park.
This really may be 2 separate switches, but should be under the dashboard and both should "open" when you push the brake pedal down.
Take a good flashlight and look.
The switches are small, about the size of your thumb, and both should have 2 wires attached to them.
Be blessed.

most likely it is ur brake pedal switch, it just behind the brake pedal arm, this switch must be triped by pushing the brake in order to shift into gear, if switch goes bad u cant shift. best of luck

I'm going to say something happened to the cable between the shifter and the transmission. There is a switch on the transmission that prevents you from starting the engine in anything other than park or neutral. The transmission is probably in reverse or drive which would allow it to roll.
Someone would need to check the lever on the trans where the shift cable is attached.

There is a safety switch inside the gearshift assy. (below where you shift the gear handle) this safety switch locks the gearshifter in park until you press the brake pedal. pressing the brake pedal is supposed to release it. obviously it's not, so there's soda, coffee, or other substances making it sticky, or it could be just worn out. Take the cover plate off & look for this plastic piece attached to a cable(covered in black plastic) if it needs cleaning, use alot of warm water & a shop-vacuum. if cleaning doesn't help, then replace the cable (may be part of the shifter mechanism.)

Do the brake light work? No brake lights and it won't shift out of park. Check your fuses and check for loose wires. Check your brake light switch. If that has failed, you won't be able to get out of park. The other one if the shift lock solenoid which is in the shifter assembly. The brake shift interlock switch prevents the car being shifted from park unless the brake pedal is depressed. Try to apply power/ground to the proper wires & see if it will activate.. If it does, then the problem is between the brake light switch & that solenoid. Could be the wires or the switch.Make sure the shifter cable is still held down in place at the shifter assembly & under the hood. It is the interlock switch that you hear/feel clicking.It is for the prior generation but may still apply.

Good Luck and hopefully you soon will be on the road again...;-)

do the brake lights work? most of the time the problem is a broken wire at the brake light switch under the dash on the brake pedal. the ECM does not see the signal from the switch so it won't allow the car to shift from park.

There is a small plasic acess cover (1/2" x1/2") on the base of the shifter. Pry it open and press the button. You should immediately be able to shift. The button is needed because the sensor on your brake pedal is broken (won't activate your brake lights either). Use the button on your shifter to get your car home or to the mechanic so you can get the brake switch fixed. Remember whern you drive you have no brake lights. -Mark
