Lock change: new mortice deadlock on an oak flat door in Westminster
On an October evening in 2026 our locksmith fitted a new mortice deadlock to an oak flat entrance door in Westminster (SW1P).
The job
- Where: Westminster, London (SW1P), October 2026
- Door: oak veneer flat entrance door
- Fitted: a 3 lever mortice deadlock
What we did
- Checked the size of the existing lock pocket in the door edge.
- Fitted the new deadlock and its keep.
- Tested the bolt throw and handed over the new keys the same evening.
Worth knowing
- Flats often need a second lock. A deadlock alongside the latch means the door is locked with a key, not just shut.
- Check your lease and insurer. Some buildings and insurers specify the lock grade for flat entrance doors. A 5 lever British Standard lock meets most insurer requirements.
