Changing & Replacing Door Locks
Common Reasons For This
A locksmith can help change & replace house lock if you have lost your keys, the lock is faulty, or are you are locked out of the house.
The most common reasons a new lock will need to be fitted range from the following:
- Moved into a new home – Moved into a new home/flat/apartment or changed business address and need to retain key authority.
- Upgrade locks to BS 3621 – Locks require upgrading for insurance reasons (for example your insurance may stipulate that locks have to be British Standard 3621) or for peace of mind.
- Lost keys – You have lost your house keys, or someone has a key that should not.
- The lock is faulty or damaged – the lock is beginning to be unreliable and can be hard to operate. (Usually either worn or faulty.)
- Keyed Alike – changing your locks to keyed alike so multiple locks are opened with one key
How to tell if my locks are British Standard?
To find out if your current locks are to British Standard, look for the BSI kitemark symbol on the faceplate of the lock, this is the part you cannot see when the door is closed.
What type of door are BS3621 standards locks found on?
The type of door is another factor, normally BS3621 locks are found on doors where the frameand door are made of timber.
- Ground floor exteriors doors usually have BS3621 Standard Locks

Can you change the lock without a Key?
Key is usually needed
A key is sometimes required to change a euro profile cylinder lock because the cam on the lock needs to be in line with the euro lock body to remove from the door.
Change the lock with no key
If you have no keys and the euro cylinder retaining screw is removed in the usual way, then the euro lock will NOT slide out as the cam is in the wrong position stopping the euro lock from being removed.
A locksmith will be able to attend site and change the euro lock even if no key is available.
Remove the lock non-destructively – They will use an array of specialist tools and knowledge to align the cam in the correct position to remove the euro profile cylinder lock without damaging the door.
KEYS CUT FOR NEW LOCK – Don’t forget when you have changed your locks to have a new set of keys cut.
