A common question we get asked quite a lot is “How do I remove an Entrance Lock Set from my door”. I just put together this quick explanation to help anyone having troubles removing the lock from the door. This is for a Carbine 3000 series entrance lock set but most tubular entrance set locks and lever handle locks can be removed the same general way.
On the inside of the door between the knob and the door there will be a small hole. This is a pin retaining hole that when depressed allows the inside handle to be removed. You need a piece of wire or pointy object to depress the pin.
Step 2 Pull Off Handle
While the pin is depressed, pull the handle and the handle will slide away from the lock. Completely remove the handle from the lock.
There is a metal escutcheon that has to be removed. This is a clip on metal plate and can be popped off with the help of a screw driver. There is a spring that stick out right next to the pin retaining hole. Push this spring in against the centre of lock and the escutcheon will easily be removed.
Remove the 2 screws that are holding the inside plate clamped to the door. The screws have a serrated head to stop them coming loose so they can be a bit hard to unscrew at first.
Remove the lock from the door. The lock will slide out of the door hole and slide out of the latch assembly.
When reassembling the lock it is done in reverse order. Be careful to align the lock body with the latch correctly. The latch has 2 flanges that must be inserted into the lock body. If they are not inserted correctly the lock will not work properly.
