Prime-Line E 2103 Cylinder Lock, 1-1/4 In., Schlage Shaped Keys (Single Pack)

The lock cylinder on my patio sliding door had finally given up. Calling a locksmith for a patio door felt expensive and unnecessary. Prime-Line's E 2000 cylinder is exactly the kind of part that makes a DIY fix possible without any special skills. The brass housing and 5-pin tumbler construction feel solid and durable. Installation is straightforward for the intended application of surface-mounted patio door handle sets, and the hardened cut-away tailpiece can be snapped at multiple break points to accommodate different door thicknesses. One practical note worth flagging: during installation in a patio door, make sure the tailpiece is oriented correctly before fully seating the cylinder. A little test rotation before final tightening saves a headache. Also, the keys that come with this cylinder are unique to this lock and are not interchangeable with your existing Kwikset or Weiser keys even though the keyway looks compatible. This is a replacement cylinder, not a re-key of your existing system. With that understood, it is exactly what it needs to be: a reliable, affordable replacement that skips the locksmith bill.

I was re-keying an electronic Schlage lock to match the rest of the locks in our home. During the the process, the back plate seperated and all of the pin springs went everywhere and could not be salvaged. Ordered these replacements, they fit in the Schlage lock just like the original and work great.

I needed to replace the key cylinder on a vinyl sliding glass door out to the deck. It's not sold in any home improvement stores near me, so I just chose a model here on Amazon, hoping it was the right one. It certainly looked like it in the picture. To my surprise, it came the very next day! Awesome. First off, it does not look like the one in the picture. The key is a different shape and the breakaway increments are bigger and farther apart than both in the picture and my original one. The key shape isn't a problem, so long as it works. It's a good thing I bought 2, though (have 2 doors that need cylinder replacement), because in trying to break the tailpiece into a half increment, I broke it too far and it wouldn't fit. Not to mention the washer holding the tailpiece in is extremely flimsy and cheap. Pulled out the rotary tool with metal disc cutter for the second time. Should have used that to begin with. We shall have to see how long the unit lasts into the future...I rarely use the locks on these doors. Pros: Fits in a vinyl patio door handle for sliding glass door. Cons: Minor differences from the listing picture, breakaway increments on tailpiece too wide, washer holding in tailpiece very flimsy

I lost the keys to my old lock and needed a quick replacement, so I went with the Prime-Line E 2103 Cylinder Lock since it works with Schlage-shaped keys and fit my door perfectly. Installation was mostly straightforward, but I did have to cut the tailpiece shorter than I expected. That part was a bit tricky and took some extra effort, but once I got it trimmed, everything fit and worked smoothly. The key turns easily and is also simple to remove—no sticking or hassle at all. The lock feels solid and secure overall. I’m really happy with how it turned out and would definitely recommend it if you need a reliable replacement after losing your keys.

I recently installed the Prime‑Line E 2103 Cylinder Lock (1‑¼″, Schlage‑shaped keys) on my sliding Pella patio door, and I'm genuinely impressed. From unboxing to locking in under 20 minutes—this was one of the most straightforward and satisfying DIY upgrades I’ve done. Easy Installation: The lock fit seamlessly into the existing surface-mounted housing. Installation instructions were intuitive and simple to follow. 2 screws held my existing door handle together. I then used a hammer and screw driver to punch out the center hole. I cut the extra actuator arm off with a hacksaw and filed down the rough edges. It fit perfectly in my door handle and secured everything back together. Reliable Mechanism: The 5‑pin tumbler turns smoothly and consistently with the included keys, offering a much-needed level of security. When securing the door handle back to the patio door, don't over tighten the screws. It will cause binding while trying to lock/unlock using the key. Solid Brass & Chrome Finish: The material feels sturdy, with a polished chrome face and brass body that resists corrosion and wear. Perfect for Replacements: If you've ever misplaced your sliding door key or your old cylinder is jammed, this is a fast, cost-effective fix. Final Verdict: If you’re looking for an affordable, dependable sliding door lock replacement and don’t mind using the included keys, the Prime‑Line E 2103 delivers excellent value and easy installation. Highly recommended!

If you look closely at my photos, you will see the difference between a genuine Schlage cylinder and this Prime-Line Chinese knock off. That slight little difference in the shape will cause your handle to pull off the door and leave you with the door handle on the floor. If I didn’t double check a few times, I may have left it without even knowing. It’s not a big deal to return this imitation knock off, but the amount of time that you’ll waste by trying to get your lock to work isn’t worth it. This should not be sold as it’s a major waste of time.

not so good,tend to have bad fit,not smooth

Works great fits well, good product.

I purchased this item and installed it in my sliding patio door. It was easy to install and is working flawlessly after a year

Used it to replace a busted schlage cylinder. The length and bits were a hair different, but the pins fit perfectly and the key turned smoothly.

Watched youtube instructions, punch out the hole. First try failed because I got it upside down. So it would not lock or unlock. After reversing the orientation, works like new.

Had to drill a hole in my existing handle which was easy to do. I fit perfectly and works very well. Took less than 20 minutes to install and out the door key in hand...

Work, but the circle is too big for my old lock, I need to modify my lock a little.
