Is you current UPVC door lock out of date of broken, have you seen a better one on a friends door and are thinking about replacing or installing one on your own door? There are a whole range of UPVC lock types available on the market. Whether you have an exterior door that you want to secure or you have interior doors that you want to be able to lock and unlock, you will find an option to work for you. 1. Multi point UPVC locks When a handle is turned, a series of roller cams secure the door. The handle can either be locked in place by a key or simply turned from the inside to lock the cams in position. The more cams that are in place down the length of the door, the more secure the system. 2. Keyed UPVC door locks Classic keyed systems will tend to incorporate a cylinder system. One reason that you should use this type of door lock is because of the level of security that is offered versus for example a multi point system with a handle but no key to secure the door. This type of lock of course requires a key to be able to lock and unlock it, so you can be sure that it will be harder for a thief to get in. It is typically installed on storm doors, patio doors, and any other type of doors that need to be safely secured.
There are also ones that require a key to be able to lock and unlock the patio door, although some combination lock products are occasionally used in a home environment although more often for business purposes. The other type that a lot of people use is called a security bar. It is built out of strong durable steel with rubber ends. This type of lock will prevent the door from being slid open until the bar has been removed from the inside of the door. Other similar bars come in a more ornate style, sometimes fitting at the base of the door, which just look that little bit better for those that are aesthetically minded. Another option is the deadbolt lock type, which often complements a latch lock. Ideally a deadbolt should be situated top and bottom of the door, to make it that much harder to pry the door open. If you are having a little bit of trouble selecting the lock that you want to use, then there are a few different things that can help you make a decision. The first thing that you want to think about is the people who are going to be using the lock.
These require a little more skill to unjam.Firstly spread the door gap carefully and hold open with soft wooden wedges to prevent frame damage. Once the location of the hooks or deadbolts are identified you can retract them manually by forcing them inwards with a strong screwdriver or bent instrument. Ensure the key has been turned into the unlock position before forcing any hooks back in place as the turn of the key is the secondary locking feature and will not allow the bolts to retract. Once the door is open you can identify the cause of the problem. usually it will be down to a failed gearbox on the multipoint lock. These contain complex cast parts that are prone to shattering and shearing when the door is particularly stiff when locking. Replacement of the gearboxes is possible on 90% of multipoint locks however some welded and riveted versions such as Millenco will require a complete locking strip. Gearbox prices can range from between £10 and £50. Locking strips more pricey can range between £30 and £150 depending on the make and model of the lock. Millenco locks feature two separate spindle gears.
