Transponder keys, also known as chip keys, have an embedded microchip that is embedded in the head of plastic. When you insert the key into the ignition cylinder, it transmits a signal to the computer system in your car through an antenna ring located on the lock of the ignition cylinder. The chip inside your car is able to receive the signal and responds with an identification code verifying that the key is the correct one for the vehicle. The car will not start unless this response is received.

The receiver interprets the code and then performs the action requested like unlocking the doors or launching the engine. Key fobs may also control other functions, like activating the vehicle's panic alarm system or disarming and arming the security system.
The radio frequency (RF) signals utilized by key fobs are similar to those that are used by cell phones. When the key fob is in the range of a receiver it transmits a small burst of energy that energizes copper coils that are located on both sides of the device. These coils convert the RF energy into electricity, supplying power to the microcomputer inside the fob. The computer then sends a digitized version of your car's unique ID number, which is verified by the receiver.

Spray the lubricant into the cylinder, then turn the key several times in both directions. The lock should be clear of obstructions and turnable using the key.
If the trunk is still not opening, it could indicate that the cylinder has been damaged and must be replaced. Locksmiths can replace the cylinder and reprogram your car key to work with the new lock. If the cylinder has been damaged during a break-in or by accident, you may need to replace the entire key assembly as well.
