Galvanized Steel Inside Deadlock, 7/8 x 1/8 (Single Pack) | Schlage Shaped Keys

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 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.

The lock worked for its intended purpose. In my case the tailpiece as to thick vertically (it didn’t fit in the slot) and required filing to make it fit. After that worked fine

Used this to upgrade the current sliding door system to a keyed one. It was easy to set this up! Good quality and compatible.

Straight garbage. First one came damaged and second as well. Second one the key wouldn’t even come off. Once I took it off I realized the lock pin in the back had come off and allowing the lock to spin freely. Save your money and hit your regular box store.

I bought two of these locks. One worked very well. It fit into the lock assembly without a problem, the key operated properly and the replacement was very easy. The second lock did not operate correctly. The screw-on nut, rear plate and rear pin assembly did not fit correctly so that the assembly basically fell apart when it was operated. No adjustments solved the problem. Because the cost is so low, the fact that 50% operated correctly resulted in 3 stars. Unfortunately I had also purchased 10 duplicate keys at the hardware store before I noticed the problem with the bad lock - these cost more than the cylinder lock.

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!

I recently got a new front entry door and storm door that has Schlage locks. I wanted to change the lock cylinder on my Pella sliding patio door to Schlage so I could use the same key for all my doors. I was a little worried because the description says "not compatible and cannot be rekeyed to match other Schlage locks, nor will Schlage keys fit into this cylinder lock." And some commenters said their Schlage keys wouldn't fit into this lock cylinder it uses slightly thinner keys. I decided to take a chance and ordered it anyway, and I'm glad I did. My original Schlage key for my entry doors fits smoothly into this lock cylinder with no problems. And I was able to get a locksmith to rekey this lock cylinder so it works with my existing front door and storm door key. Now I have one key that opens my storm door, front door, and patio door. Mission accomplished.

easy to install

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.

Easy to replace. Easy to size. I have no experience changing locks but this was very simple. Saves the money you'd normally pay for a new complete sliding door handle. Which is like $50+ CAD. I only gave it 4 stars because I'm not sure how it will act in -35 weather. Cheers!

Needed to rekey a lock. This fit perfectly.

Lock rotates smoothly.
