All you need to know about replacing a door lock including materials, labour and time frames.
Improving door security is something many are interested in today in the UK. Although replacing and/or upgrading the locks is the most popular way to improve door security, it is not the only way to do so, though this article will concentrate on door lock replacement. In the UK, Yale locks are the most common and they are self-locking by just closing the door. Though these are popular, they are not very secure and can usually be easily destroyed by using force. Deadlocks are different as you must turn a key to lock them, most often used at night or when you leave the house for a prolonged period of time. Deadlocks when used in conjunction with Yale locks are considered to be pretty secure.
One advantage with Yale locks is that you can just change the cylinder and key rather than the entire lock to save money, whereas deadlocks are usually sold and fitted as one unit. Many household insurance companies will give you a discount on the premiums if you have secure lock fitted, so when changing locks, you should contact your insurer to find out which types will save you money. The most common types of lock that is considered secure by most insurance companies is the five lever mortice deadlock confirming to BS 3621. If your Deadlock is a five lever device conforming to these British Standards you will probably get a discount off your home insurance.
Contrary to popular belief and TV shows, how resistant locks are to picking is of secondary importance, the most important security aspect is the actual physical strength of the door and the frame. If you are changing locks after a break in and there are splits in the frame where the door has been forced open, then in addition to new locks, you must get the door and frame properly repaired by a carpenter. Very few thieves pick locks, certainly not mortice deadlocks, most break-ins are in fact literally that, the door gets kicked in and broken.
If you are considering new locks to improve security, possibly after a break-in, then there are other related jobs you should also consider. having an impenetrable door is not much good if the windows have no/poor locks. So have a security expert check all points of entry and advise on locks. In addition, you might consider an alarm as an extra layer of security, plus a possible deterrent. Be careful with cowboy tradesman who present themselves as locksmiths but have no recognised training, qualifications or trade membership. These cowboys will always recommend the most expensive option, or at least the fix that will make them the most profit in the least amount of time, they are not concerned about your security!
When taking advantage of any discounts from your insurance company regarding door locks, you have to be extremely careful you are 100% sure you have the correct locks as stated on your insurance policy. If your locks differ from the insurer specification, then your insurance company may invalidate any claims that arise. You should of course take advantage of any premium discount for secure locks but it can be difficult to ascertain whether you have the correct locks as specified by your insurer, most Yale locks all look the same unless you are a locksmith!
The average cost of replacing a typical deadlock installed in a wooden front door will cost around £150, including parts and labour. Replacing just the cylinder or a Yale door lock would be slightly cheaper, say around £125.
