Depending on the system, the vehicle may start with a correct rotation but invalid key, or it may not crank. Your problem us most likely a defective key, however the immobilizer antenna could also be weak and not properly picking up the key. Both problems will require a dealer or technician or locksmith with special tools to learn new keys to your immobilizer.

Quite a lot of cars have automatically locking doors - when the car reaches around 15 mph the doors lock or a minute after the ignition key has been removed. Other than these times the system must receive a lock doors command either from the plip or by using the key to lock the driver door and sometimes the front passenger door.

You didn't say whether the problem was happening while the car is moving or when stationary but that aside, when a command to lock the doors has been received the system will attempt to comply but if it can't comply it will often make subsequent attempts and sometimes it will keep attempting to lock the doors.

Usually the reason it can't comply with the command is because a door isn't fully closed or the system thinks a door or the tailgate isn't fully closed because at least one of the devices in each door that should tell the system all the doors are closed isn't working.

That device on some cars is a switch buried in the door catch that is operated when the door striker is fully engaged in the catch. Often maladjustment and a lack of lubrication causes an abnormally high degree of wear in the catch and especially of the striker preventing the striker fully entering the catch and operating the switch.

Hyundai released a technical information bulletin regarding P2106 and that should be addressed first, if you can find it.

When the check engine light is switched on it means the closed loop system is switched off and the engine is running on the get-you-home programme.

The codes you are reading are manufacturer specific and better results are usually obtained using dealer level diagnostic equipment.

Sometimes the codes don't clear themselves after a repair. If the codes aren't erased the brain assumes the faults still exist. Throwing a new part at a problem before knowing the part is faulty is expensive, especially when the code could be caused by poor connections or wiring problems.
