FAQs
Can I change the lock myself?
Some locks can be fitted by a competent DIYer, Harold explains, “Yes, in many cases Basic Euro cylinder replacement on uPVC doors is relatively easy.” However, it can go wrong. “Improper sizing or fitting can compromise safety, and you should ensure that insurance requirements are met where necessary, so it is always recommended to use a professional.”
Dunn points out common mistakes: “The biggest DIY pitfalls are incorrect measurements, which can make the cylinder protrude and become more vulnerable, or a cylinder that doesn’t seat properly, affecting safety and sometimes insurance expectations.” “Mortis locks, nightlatches and multipoint mechanisms are generally better left to a professional,” he adds.
Does the locksmith fit the locks purchased by the customer?
A locksmith may fit the lock you supply, but this may affect your warranty. “Many locksmiths will fit locks supplied by the customer, but only expect a labour-charge which usually reflects the unlocking or fitting visit, often £70 to £120 depending on complexity,” Dunn explains.
“It’s also common for locksmiths to limit or exclude warranties on parts they don’t supply,” he adds. It is worth noting that the locksmith may not fit your lock. “Some will refuse items that are of poor quality, incompatible with the door, or unlikely to meet expected safety standards.”
Does home insurance cover changing locks?
This will depend on the type of insurance policy you have. “Many policies will cover key theft or lock changes after a burglary, but lost keys are often only covered if an add-on is chosen,” says Dunn. “Usually you will be covered when the locks are damaged due to another insured event such as fire or vandalism,” adds Harold.
Dunn shares that you also need to consider excess limits: “Typical claim limits can range from around £500 to £1,000, and policy excesses generally apply, which can make smaller claims less suitable.”
What is rekeying and is it cheaper than changing locks?
Harold quickly explains what rekeying means: “Rekeying is changing the internal pins of a lock so that the old keys don’t work and the new keys do.” “This type of work is common in commercial/master key systems, which are set up with keys and locks in mind that need to be updated,” he adds.
Dunn explains how much you can expect to pay, “In UK homes, this often means swapping or re-pinning the cylinder or re-taking the mortise lock. It’s usually cheaper than replacing the whole mechanism, especially on multipoint doors.”
He adds, “A cylinder change or key similar setup can typically be fitted for £60 to £140, while replacing a complete lock or multipoint strip can run £120 to £250 or more depending on parts and labour.”
