Boot is not supposed to open with door unlocking feature. Rear passenger door lock may be stuck. Does it work manually?

Sorry I am not familiar with the model.

Most cars of 2013 vintage use an electric release for the boot or tailgate and often there is no other type of release. If this is the case it is worth checking the vehicle handbook for the possibility of an emergency release.

When the electric release doesn't work, depending on the level of sophistication of the system, it could be a fuse, faulty wiring, faulty release button or switch or a faulty lock release motor or solenoid. It is unlikely the lock is faulty.

The last time I encountered a non-opening boot I had to remove the rear seat and wriggle into the boot and remove the boot lid trim panel and locate the wiring in order to connect an independent 12 volt supply direct to the lock solenoid. Once the boot was open it was a simple matter to replace the switch.

The previous time was similar except the problem was a worn lock and the time before the wiring had broken inside the harness where it jumped from the body to the tailgate.

This is either a bad solenoid in the latching mechanism or a broken wire that supplies current to the latching mechanism.

Don't worry I'm sure you will get the solution of your problem, just check the link I attached Hyundai I30

which door, please be specific on the problem. It wont unlock or froze shut, what were you doing when you tried to open it. Are the handles free?

Check the switch position. See if the light goes out if you manually depress the switch. If it does, raise the switch

the solenoid needs replacing, Hyundai have a seven year warranty so just take it back to the dealer & have the job done for free.

I have a damaged Hyundai I30 door can I just replace the outside shell of the door ?
