PACLOCK | UCS KA5-5 | Keyed Alike Cylinders | Pack of 5 Cylinders | with 5 Keys | Starter Pack | Anti-Theft Device

These key cylinders make it easy to change the key on your Paclock. The procedure is very easy. Loosen the set screw on the back of the lock with the included hex wrench when the lock unlocked. Slide the old key cylinder out and the new cylinder in. Tighten the set screw snd you’re done. The kit includes five cylinders and matching keys. If you have a collection of Paclocks with random keys, this is an easy way to make it so the same key works all of the locks.The cylinders have six pins and some pins have features so slow down lock picking. The build quality is pretty good. These cylinders look like a standard design, but I don’t know if the cylinders would fit other brands. I recommend these cylinders if you want replacements for your Paclocks.

Lock core is in working condition after 2-3 years, quality made American part!

Bought this to change some locks over but didn't realize this is the "Starter Pack" they send you a random key bidding and cylinders to match. If you already have some of their locks already get the other option that has the customize now button. As far as the product itself its top quality with service to match. If what you are locking up is worth anything they are my go to product for security and service. No point in buying something nice if you are just going to buy a master lock.

These are expensive compared to Master, but you get a lot more for your money. I’m half convinced to switch all of my locks over.

Shame you have to buy this many to only need ONE

Company's website directs to Amazon for sales, link with a lock and the cylinder directs to a page selling just the lock, without the internal cylinder, on a job where I needed the entire lock and paid next day shipping to get it right away. Never received a response from my email to the company. Had a lock body but no cylinder and had to then turn around and order these with separate next day shipping to get what I needed. Product worked, but overall interaction with the seller/manufacturer was subpar. Neither lock body nor the cylinders came with the required screw to attach them, I had to find one to fit at a hardware store.

I bought these for my locksport hobby and got the keyed alike variant since I'm pinning them up for a fun progressive challenge. Paclock's pin expansion set added to this makes for the perfect setup. If you're not interested in re-pinning them, they offer enough of a fair challenge as they are, or you can buy the set of them that come pinned differently. The KA set I bought can with very good bitting on the keys, so picking through them stock will keep most people busy for quite a while.I don't have any padlocks from Paclock yet to put them in, and I don't pick using a vise, so I found some inexpensive SFIC housings to put them in. They can't function as intended in them, but it makes a perfect way to hold them as opposed to holding just the small cylinder.If your reason for buying these is for security, then you've made the right choice! Paclock is far ahead of the competition. Their locks are very well made and they actually care about their customers as well as the locksport community. I'm going to continue being a customer of theirs and I look forward to their future offerings.
