Some locks we have come across haven’t been installed properly and can be opened with a piece of plastic like a credit card. This is because the lock is too far away from the strike (which is the part that the latch goes into on the door frame). This is can be easily fixed so that you can avoid a costly break in or damaged lock mechanism.
If you are concerned, take a photo and send it to us, we can let you know, saving you time and money.
