![]() It remains stationary at all times, even when the proper key is used to open the lock. Without the proper key, the plug will not spin and the lock will not open.īible – This is the housing for the plug. This rotation moves a stationary tailpiece or cam on the back of the plug, which will actuate a bolt, latch, etc. It holds the keyway and rotates when the lock is open. Plug – This is the part of the lock that the key is inserted into. The reason this uniform height matters has to do with the construction of a pin tumbler lock. A shallow groove on a key needs to line up with a longer key pin, and a short pin will need a higher groove so that all the pins can rest at a uniform height. This is why the key tumbler (key pin) and key need to be made for one another. For a lock to open, the pin stack (tumbler stack) needs to be elevated to a particular height by the proper key. In order to know the difference between lock tumbler replacement and key tumbler replacement, you need to comprehend these parts make a lock work. In terms of lock tumbler replacement, driver pins are often swapped out for pins of a different shape (though not a different height). For that reason, they rarely wear down and are not involved in something like a key tumbler replacement. They are a standard height and do not touch the key when it is actuating the lock. If you wanted to get a lock to open with a different key instead of a general lock tumbler replacement, you would use key tumbler replacement (more commonly referred to as “rekeying”).ĭriver Pins – The driver pins rest sandwiched between the key pins and the springs. Unless the key is made with the key pins’ sizes in mind, it will not open the lock. (Though they are called pins, this is a word used interchangeably with “tumbler”.) The key pins are cut to different heights that correspond to the varying groove depths on a key. Key Pins – The tumblers/pins that are touched by the key are called the key pins. Springs can be made of different metals to provide a variance of pressure, but they are often standard within most locks. The spring places the stack under pressure so that pins reset fluidly after they have been raised by a key. ![]() Springs – A pin stack is made up of at least two pins and one spring. Inside a basic pin tumbler lock you have several pin stacks (most often five). In order to understand the various ways you can approach lock tumbler replacement, you have to understand what parts of the lock are being replaced and how they are important to the lock’s functionality. These parts of the lock are what make certain keys work in the lock and keep all others from opening the lock. Tumblers, also known as pins, are the internal components of locks of the pin tumbler variety. Find out the options for your locks and how lock tumbler replacement can help you to achieve your goals. The possibilities go beyond simply rekeying your locks by the means of key tumbler replacement. There are many things you can do with door lock tumbler replacement.
