Car will not shift into reverse, where is the manual override switch and how do I check it?

If you're unable to push the gear shift into neutral in a 2007 Chrysler 300 when the car battery is dead and the key has stopped working, there is a solution that can help. You can locate the shift interlock override mechanism to manually put the vehicle into neutral. First, remove the plastic cover or cap located near the gear lever to reveal the shift interlock override slot. Insert a small screwdriver or a similar tool into the slot and apply gentle pressure while simultaneously attempting to move the gear lever into neutral. This should release the shift interlock mechanism and allow you to shift the car into neutral. It's important to exercise caution and consult the vehicle's manual for precise instructions tailored to your specific model, as the process may vary slightly.

the brake light switch controls the shift lockout solenoid. perhaps this brake light switch is ajar or misaligned or inoperative. check to see if brake lights are working. there is an override to the shift lever lockout.

what car, you never said? NOR YEAR?
park lock out feature;. its broken , they do that. (BTSI system)
got A/T? or M/T both auto and stick shift have lockout.

no car/year, you get the generic answer.
there is a park lockout DEFEATER on most cars, (never on new cars,due to federal bs)

on the shift console, see the defeat device.
the operators guide covers this. its for EMERGENCIES.
pick one.

the A/T box,
Brakes + handle button press, unlocks BTSI

on 2005 and up , no bypass
if the key gets locked too, that tells you what is bad , on newer jeeps

this feature (pain) has many failure points.
any cable that jams, there are 2 , one to tranny or ignition
switch. and the brake solenoid unlocker in shift handle.
and the button, to unluck shifter, brake switch (no brake lights/)
to diagnosis it is easy , dismantle the console at shifter
then disconnect cables to find if one is stuck, (easy huh?)
and defeat the solenoid, by hand or 12v applied. and check the button
that it does in fact release.
NOT PARK LOCKOUT: (for if not on flat ground?)
reason 2 , driver, parked on a hill with tire to curb and did so
not setting brakes first (or bad ebrake ) and now the tranny parking
pawl is jammed , opps. so wiggle the steering and wiggle shifter,
or have some one push car forward (parked up hill on right) to release
parking pawl. (or gorilla it, ask bubba to muscle it out of park.)
if down hill , well, you get the idea..... pain.. gotta love A/Ts not.
Folks in Sanfranciso, just roll eyes at you, new in town>?

now the grand cherroke,, why not post car model, and year, dang.

Brake/Transmission Interlock Manual Override Your vehicle may be equipped with a shift lock manual override. The manual override may be used in the event that the shift lever should fail to move from PARK with the ignition switch in the ON position and the brake pedal pressed. To operate the shift lock manual override, perform the following steps: 1. Turn the ignition switch to the ON position without starting the engine. 2. Firmly set the parking brake. 3. Using a flat-bladed screwdriver, carefully remove the shift lock manual override cover, which is located on the PRNDL bezel. 4. Press and maintain firm pressure on the brake pedal. 5. Using the screwdriver, reach into the manual override opening. Press and hold the shift lock lever down. Interlock Manual Override end quote.
no all jeeps have this,

check the fuse for your brake lights, check your brake light switch. If the brake lights don't go on your car will not shift out of park. The shifter should have an override button. look for an access hole (cover) near the shifter, pop the cover off and push a pencil down there to shift. check your owners manual for specific information on the use of the override button

It probally has an electronic shift control unit.I had a Honda Accord that did the same thing. It was located under passenger side floor mat. The unit would keep it from shifting out of gear,it overrides the manual override. I would call a dealer and ask if your car has one. But I say 70% chance your car has one too.

The brake/shifter interlock switch is bad. You can manually override the switch. Your owner's manual should have instructions on overriding the switch.

check your brake lights also, if none then you need to repair the wire that connects to the brake light switch at the brake pedal.....and or replace the brake light switch

Sounds like you need a new shifter assembly, or the brake switch. Most likely will be the shifter though if you can move it out of park with the override.

When you experience this problem, check to see if your brake lights are coming on. It could be as simple as a brake light switch malfunction. If the brake lights are functioning as the problem is occurring then you could for example have a problem with the shift interlock solenoid.

shift lock switch needs adjusting or replaceing, there should be a manual override at the shifter check your owners manual
