I have a 2010 Santa Fe, the passenger side front door will not open from the outside. When you unlock the doors the door will pop open.

You may need to replace the power lock actuator motors inside the door . Alternatively, you can try disassembling the paneling on the left side under the steering wheel and removing two black relays on the side closest to the steering wheel. Then remove the relay covers and clean the contacts with a 1/8 fine strip of 600 wet/dry sandpaper.

I had exact problem Santa Fe 2007 2008 lock was stuck in locked position and door would not open from inside or out. All other doors would unlock with auto key remote. Carefully work the inside lock towards the open position as you lock and unlock the door with the remote. As you press unlock try to assist the lock to open. I did this a few times and the lock became free to the open position and all worked perfectly after this.

see if the manual lock will unlock make sure the door is shut properly it may be jammed or not set completely

Your door lock actuator have issues

i had a problem not unlike this in my santa fe 1.9td uk spec.
my car had been sitting for a few months and when i returned to drive it again the same problem came to light.
i also rep[lsaced the key fob.
it could be one of two things.
firstly the systen might neen re-set. if you disconnect the battery for 2 hours then attach ti again it might work.
if this fails it might be the actuator in one of the doors. if it is faulty then it only semi closes the lock, but it then thinks that has to lock again. and locks the door.
hope this helps.
