Can the lock on an old security door be changed?

Yes, it can almost always be done, even if it is a lever lock or a model that is no longer made. There is no need to change the door.

There are three usual routes:

• Fitting a new lock that fits the same recess, if a replacement with those measurements exists.
• Converting the lever lock to a cylinder lock, which is usually the most practical option if the key is one of the big ones with long bits.
• Changing just the cylinder, if the lock inside is in good condition.

To know which one applies, the quickest way is to send us a photo on WhatsApp of the edge of the door with the lock in view and another of the key. With that we identify the model and give you a fixed quote. We explain it in lock replacement.

On old security doors it is also worth checking the hinges and the frame: a new lock is not much use if the door gives way somewhere else.
