Let’s Discuss Pins! 

When it comes to pin and tumbler locks, it is important to note that reconfiguring them is possible. This process enables them to be a match for a key that you might already have. This is beneficial for both residential and commercial customers in the sense that they can use new locks without needing several new keys. You can modify a lock so it becomes a fit for a key that you might already have in your possession. This would entail switching the pin pattern in the lock in order for it to match the pattern of key notches. Pins in locks are also a way that a locksmith might work to rekey a lock. 

Lock Rekeying – How this is Related to Pins 

Rekeying a lock involves an experienced locksmith taking the pins out of the cylinder and then using replacement pins in different sizes that fit between the shear line and key notches. When a new key is used, the lower pins press the upper pins over the shear line. There are different lock designs, of course, and as such, there could be some variation in this process. Master keys and pins are unique.  

When it comes to locks, no matter the type, you will find that for the most part, most are made of the same parts. This would entail approximately 12 pins a well as springs. The top pins (six) would be the same size, whereas the bottom pins might be in different sizes which is so they can be a match for your key’s grooves. Springs are there to hold pins where they need to be. Hopefully, you have a better idea of how pins work and how this would be relevant when it comes to master locks. 

Are there any potential concerns with master key systems? The short answer is yes. When it comes to master key systems, master pins are placed inside a lock’s cylinder. When this is done the security of said lock can be compromised. A lock like this might be easier for a criminal to break through or otherwise manipulate. It is important to note that master keys and locks were largely made for convenience. Having locks rekeyed can be a good idea if yours have master pins, but we recommend high security locks for installation if you need master key. This can offer more security.  

Master key and lock systems can be considered a bit less secure than other options out there. If the master lock and key are being used for a certain purpose like locking a shed rather than a front door, this might be a good idea for you. Some consider poor planning to be involved with master key and lock systems. When it comes to traditional pin tumbler locks, the master key for them can be misused by probing each chamber’s pin stack. Mechanical bypassing could be possible. What is the better option?
