My car Wont open even when unlocked or with key

I think the system on that car enables you to open the petrol flap once the drivers door is unlocked (either by pulling the cap open or pressing on the flap).

1. Lock the car using the central locking.
2. Insert the key on the drivers door, turn it once and unlock it. Open the door to check you have unlocked it. Then turn the key in the lock again as if you were unlocking it a 2nd time.
3. Now open the petrol flap as the lock should have released.

although you can open the door with a key ,unless the alarm system senses a fob key signal it will assume that the door is being opened illegally and will set of the alarm
keys can be cut for all cars requiring a key fob unit but the alarm is not cancelled and the engine will not start
you may have to get another key fob and have it programmed to the ECM system

It sounds like the key sensor in the drivers door is malfunctioning, the drivers door is the only door that can enable/disable the alarm, if you try to unlock any of the others it will trigger the alarm.

Sometimes with my Kia I have to (without opening the door), cycle lock and unlock several times before the alarm is disarmed.

Have you tried this is succession, with all the doors locked:-

put the key in the drivers door, turn to lock and then to unlock, the alarm should disarm.

Also, if any of the door locks are jammed, the alarm will still activate when you try to unlock the drivers door.

If that fails and the alarm still activates, then it's a problem with the key sensor in the door.

I'm not a car mechanic, but, it sounds like you might want to check the fuse to the ignition switch, and, if that fails, it might be a problem with the Start Safety Switch on the transmission. Good luck.

Is it the proper size battery as this happened me also. The battery was slightly too high even though it fitted in the key chain. So it was actually the wrong battery. I changed this and now it has the right battery but makes a loud horrible noise when I lock my car and when I unlock the car, it unlocks all the other doors except the drivers door, which means I have to get in the passenger side to open the drivers door. I am bringing it back to the garage to try and sort this annoying problem out,

your key, even if there was only one issued with the car when it was new, should unlock the door. this issue may be due to a dead battery and the car is unable to read the transponder code that is sent from the chip in the key.if none of the fob buttons work and the key wont open the door you may have to have a roadside service tech. open the door manually with a wedge kit. this will at least get you in and then you can pop the hood to have the battery checked just be sure the tech who comes can do both unlock the car and check the battery to be sure your not charged twice for the same problem just explain the situation when you call for help hope this helps that's all i can think of on a car this new.

Typically, the steering is preloaded. This happens when car is turned off with some steering assist being applied (whether you know it or not).

Often you have to manhandle the wheel in one direction or the other while turning the key.

sounds like you need to replaced the latch in the door. or like my 06 cobalt lt the door was bouncing and not closing all the way, or not opening. they cleaned my latch and i havent had a problem since, but that latch in the door could be your problem.

A rubber boot around the lock motor can disintegrate and get caught up in the motor gear or if the link age assembly to the motor gear has been fixed with epoxy glue ( allowing no free play) then these symptoms can develope which allows the automatic door locks to work but very stubborn almost impossible to open manually.
