A remote key fob needs to be associated with your vehicle particularly in order to be secure. This stops people who drive the same make and model of automobile as you from using their remote to access your car. You’ll need to reprogram the fob if changing the batteries has erased this connection or if it was somehow disrupted in order for it to once again recognize your automobile.

Make Sure You’re in Park (parking mode)
Are you sure you’re in park? I know that sounds dumb and very, very common sense. If so, the automatic transmission in your car probably won’t let the key out unless you put it in park mode. The shift interlock, a safety mechanism, is to blame for this.
Wriggle Your Steering Wheel to Get the Locking Steering Column to Release the Key
Most cars have a locking steering column as an option. Once you take the key out of the ignition, it will lock up. That is intended to deter car thieves. If the locking steering column malfunctions, excessive pressure is applied to the ignition switch, which keeps the key in the Corolla locked.
You can get your key while your vehicle is in parking mode by turning the steering wheel.
Disconnect the Power to the Solenoid
Don’t worry if the aforementioned suggestions haven’t worked thus far. Sam Carmel, the proprietor of Corolla, claims in a “>YouTube video that the starter solenoid found in Corolla vehicles may hold the key (no pun intended) to resolving your problems. This solenoid activates the starter motor of the car by acting as an electromagnet. Two lengthy cables from the starter solenoid connect to the starter motor.
By cutting the wires, you should be able to turn off the solenoid. In the 2010 Corolla, at least, where Carmel focused for his film, the solenoid is located behind the steering wheel. He claims that modifying the solenoid is secure. Hopefully, that will produce the key.
Test Your Car Battery Life
Your Corolla can’t operate without power if the entire interior, including the ignition, is electronic. That usually means that if your automobile battery dies, your key could become seized. There are two clear signs that the problem is with the battery. Do you first notice any inside lights? Can you also start the car?
If the response to either of those two queries was no, your battery has likely died. If you’re not at home, you’ll need to acquire a jump. In order to avoid getting into another awkward situation, make sure you monitor your car battery in the future.
Confirm Your Ignition Lock Cylinder Is Properly Working
A device known as an ignition lock cylinder is found in many vehicles. This is arranged in a row with many pins. When you insert the key into the ignition, a spring inside each of these pins can be released, holding the key in place.
These pins are far from flawless, much like every component of a car. Your key won’t come out of the ignition if there is misalignment or if any of the pin springs become stuck and unable to retract. Smack your ignition lock cylinder with a small hammer, but do so very carefully. After all, you don’t want to damage it. With any luck, a few solid blows will get everything going. If not, a new ignition lock cylinder is probably in order.
A clean ignition lock mechanism is also important. You might have trouble getting your key in or out smoothly due to gunk and particles.
Call a Tow/See a Mechanic
In the worst-case scenario, you might need to call a tow truck to have your car towed and yourself sent home (or work or wherever you were going). If you tried all of the aforementioned fixes and they had no effect, then that is. Most likely, there are deeper issues at play than you can address on your own. Allow a mechanic to handle it.
