uPVC Door and double glazing multipoint locks are prone to jamming shut where maintenance has been neglected or the weather prevents the mechanism in the door working smoothly. Depending on the type of uPVC door lock fitted in the door there are various methods of unjamming.Our locksmith found that cheaper doors are usually fitted with roller type locks.These locks have rollers that slide up and down into keeps when the handle on the door is lifted upwards.These doors can be unjammed using a wide flat steel bar or door spreader. The rollers will easily pop out of the keeps unjamming the door when a spreading force is exerted. This is also considered a security flaw in older uPVC doors since it is such an easy method of opening the door. Our locksmith found that on the more modern and expensive makes of door, hook and deadbolt style multipoint locks are fitted.
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.

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.
