Got into my 97 crown vick today crank it up depress break as always went to shift to reverse and it was locked into park try to no avail do you have any ideas whats wrong

You could have a shifter switch problem...check on the brake pedal depending on your car it might have 1 switch with 4 contacts;2 for the stop lights and the other 2 for the shifter release solenoid which might fail.You can contact a test using a voltemeter yo check for continuity on all terminals 2 @ a time.Then some other cars have 2 switches 1 for stop lights and the other for the shift solenoid.The other important thing is to check fuses,if non of the above doesn't work then U might need to open the centre consol to access the actuator that kicks open the locking mechanism and check if its not fried

Check your brake light fuses

There are multiple issues here.Won't crank? Go direct to starter.

Check your linkage bushing. Those tend to break, very cheap fix, Dorman makes a replacement.

Generally,when a shift lock solenoid/system goes bad you just zip tie the shift lock to unlocked position and that removes the need to depress the brake to shift out of park.

It has a brake-transaxle shift interlock. You should just push the brake in to shift, but if you have done that, and it still won't shift, with foot on the brake, push the shifter all the way into park. Sometimes they don't always go into park all the way. Also if you park on a hill, it puts pressure on the btsi, so you cant shift it. Have someone push the vehicle back, just enough to take the pressure off and it should shift. I had this happen to me with my Grand Am.

Based on the information you have supplied, the car is not shifting in to the correct position. So when you try starting the car , it will not allow the starter to crank thinking it is not in park (which it is not...in reverse) I suspect that the shifter cable from lever to the transmission has become stretched over time and use. It can be adjusted at the transmission to shift cable hook up. The connection at the lever base could have also get disconnected. Try that first

EITHER IT IS CONNECTED TO THE TRANS BY A ROD OR CABLE SOMETHING HAS COME LOOSE THERE

Is there any warning lights or malfunction besides this?? There are three main parts that may cause this: Park/Neutral safety switch(located on the transmission), Brake pedal switch(located at the brake pedal), Shift lock solenoid(located below the shifter). P/N safety switch prevents the shifter from shifting out of (P) or shifting into (R/P) while vehicle is in motion. Brake pedal switch sends a signal to release the shifter lock to shift out of park. Shift lock, locks the shifter as describe above and is located at the shifter base. I recommend inspection/replacement of the shift lock solenoid and P/N safety switch as its an intermitted problem. Hopefully this helps

If brake pedal sensor is bad, then lever cannot be taken out of Park unless you depress the shift lock near base of shift lever - pop off small rectangular tab to access.

Burned out brake light bulbs will not affect the shifting.
