Key stuck stuck in park

You should take your car back to the person or place that you fixed it and tell them it is worse than before. Insist on getting your money back if it is not fixed.

Could be the brake switch or the shift lock solenoid. You may be able to turn the key lock to the unlock position, move the shifter out of park, then start the engine in neutral.
The shifter and the shift lock solenoid would need to be inspected.

The first thing to do is check the brake lights, it they are not working the park lock system will not release the shifter.

Gear shift is not totally in the park position - had the same problem with a 2011 Acura TL - a rubber band kept the gear shift lever from totally seating in the park position.

Had a similar problem. Solved it two ways first place key in the 3 position move gear to N then start and it will shift easily. Second solution check brake light fuse, it is probably blown replace it and gears will shift OK.

Most newer models have a safety feature called
shift interlock. This prevents the key from being turned back
to the lock position if you forget to place the gear selector in park.
Depending on the model,
If it uses a cable, it may be sticking or needs adjusting.
If it uses an electrical solenoid. may be blown fuse or park switch.
Tap, shake, and pull up on the shifter and make sure it's in park.

I have the same problem few days ago, and still didn't find any solution. Can any one please help?????6

I suspect your battery is dead. The key won't come out unless the car is in park also.. and might even require power from the battery to get the key out.. I would start with a jump to the battery and see if your key issue is solved.

when you start it if you press brake will it select gear

i dident read all but the car won't go in to gear if the car dos'ent sence you pressing the brake its a safety thing check brake fuse thats seems like what is happing if you nned to the switch for the brake is right above the brake pedel it should have to wires to it but it could be a fuse
