How do i open my lock when i don't remember the combo?
Start guessing.
Most cheap locks aren't that sensitive, so you don't have to try every number. The sort used in school lockers will probably open if you're within 3 of the correct value, so you can try every fifth number. Of course, if it's a school locker, you could just go to the office and get the combination again; they record this sort of thing.

How can you fix a stiff car door lock?
It depends on what the indicators are. Usually lubricating the lock with spray lubricant like Triflow or WD40 work. Never use graphite in locks as it tends to get clogged in the springs. If the lock is difficult to turn after this, then there might be a linkage problem which would require removing the door panel and finding the bind or other issue.
How are electromagnets used in door entry systems?
The door entry system consists of an intercom (with or without a camera) - a switch and an electromagnet.
The electromagnet holds the door closed so long as current is flowing. When someone requests access (usually by use of a call button) they speak to the person inside the building via the intercom. When the person inside is happy to let the person in, they press a switch which disrupts the current to the electromagnet. This releases the door so the visitor can walk through. Doors usually have a powerful spring to close the door behind you when you walk through.

How do you open a door without a knob?
It entirely depends on where you are and what is surrounding you. If you are trapped somewhere with a large object, you could lift it and ram the door down. Or if you are near tools you could pick the lock maybe even with a bobby pin.
well if it's not locked and the door knob is not there and there is just a hole and the locking system is still inside the door you simply put your finger in it and like a door knob twist it
in the bottom right inside the hole you will feel a slightly sharp edge you need to push that down and push or pull the door at the same time.
Will a remote key operate the doors if another remote key is in the car?
No the other key will not operate the door when another remote key is already in the car.Same key has to be used to operate the doors.
Edit(razor512):
If a car comes with 2 remotes for the alarm and the door locks, then both can work at the same time, even if one of them is inside of the car.
The area where things get tricky is if the remote for 1 car is working on another car. In which case, the factory used the same code on more than 1 car, or someone used a radio monitor able to listen at the frequency that the remote runs on. The signal sent out by the remote is then recorded and replayed in order to spoof the remote. (this is why it is not the best choice to get remote starters, someone monitoring the frequency range can pickup the door unlock signal as well as the remote start signal, then replay it in order to do malicious things to the car (though this should be rare since most criminals are idiots)
Why won't a car door lock when you shut it?
Some models force the driver to hold the door handle out as they lock it to prevent the operator from accidentally leaving their keys in the car. Usually cars with this feature will beep if the keys are left in the ignition, to bring even more attention to the mistake.
