When Should You Change Your Locks?
There are several situations where changing your locks is strongly recommended. After moving into a new property, as you have no way of knowing how many copies of the old keys exist. After losing your keys or having them stolen, as someone could use them to access your home. After a break-in or attempted break-in. When your locks are old, worn or difficult to operate. After a relationship breakdown where an ex-partner has keys. When your insurance requires a specific lock standard. If any of these apply to you in the South West, contact a local locksmith sooner rather than later.
Lock Change Costs in the South West
The cost of changing a lock depends on the lock type and the door. A standard euro cylinder lock change (the most common type on uPVC and composite doors) costs around £60-£100 including the lock and labour. A mortice deadlock (common on wooden front doors) costs £80-£130 to replace. Changing a full multipoint locking system on a uPVC or composite door costs £120-£250. These prices are typical for a locksmith visit during normal hours in the South West. If you need multiple locks changed, most locksmiths offer a discount for doing them in one visit.
Types of Door Locks Explained
Euro cylinder locks are the most common on modern uPVC and composite doors. They slot into the door and are operated by a key from outside and a thumb turn or key from inside. Mortice locks are fitted into a pocket cut in the edge of a wooden door. They come in deadlock (key only) and sashlock (with handle) versions. Rim locks (like Yale locks) are mounted on the inside surface of the door and are common as secondary locks. Multipoint locks use a single key to engage bolts at multiple points along the door edge, providing stronger security. A locksmith can advise which type is best for your doors.
What Lock Should You Choose?
For the best security, look for locks that meet British Standard BS3621, as most home insurance policies require this. Anti-snap euro cylinders are essential for uPVC and composite doors, as standard cylinders can be snapped open in seconds. Look for locks rated to SS312 Diamond standard by Sold Secure or TS007 3-star rated. Popular brands include Ultion, ABS, Avocet and Brisant. A good locksmith in the South West will stock quality locks and can advise on the best option for your door and budget.
Can You Change Locks Yourself?
Changing a euro cylinder lock is relatively straightforward if you are handy. You remove a screw from the door edge, turn the key slightly, and slide the old cylinder out. The new one slides in the same way. However, getting the correct size cylinder is crucial, as an incorrect size leaves the lock vulnerable. Mortice locks are more complex and best left to a professional. If you are in any doubt, a locksmith can do the job quickly and guarantee the work, which is worth the cost for your home security.
Frequently Asked Questions
How long does it take to change a lock?▼

Do I need to change locks when I move house?▼

Will my insurance cover the lock change?▼
If the lock change is needed due to a break-in, theft of keys, or loss of keys, your home insurance may cover the cost. Check your policy, as many include home emergency cover that pays for a locksmith. Keep all receipts for your claim.
Can a landlord change the locks?▼
