How Much Does a Lock Change Cost?

A standard lock change typically costs between £80 and £150 including parts and labour. Anti-snap cylinder upgrades for UPVC doors start from around £100. Keys4U provides fixed, transparent pricing — you'll always know what you're paying before we start.

Choosing the Right Replacement Lock

For external doors, always choose a BS3621 approved lock. For UPVC doors, upgrade to an anti-snap, anti-pick cylinder rated TS007 3-star. Keys4U can advise on the best option for your specific door and security requirements.
