Prime-Line E 2000 Cylinder Lock, 1-7/8 In. Tailpiece, Fits Weiser®, Kwikset® and Weslock® (Single Pack), Bronze

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!

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

This replacement cylinder is good quality and I have no issue with it as advertised. But just as a warning to others: it looks like it might be the same as a cylinder from a Schlage Encode smart lock. It is very similar but it will not fit.

Wow! It fit my vintage sliding door handle perfectly! Works great! You better be a handyman if this is a new install tho... my door didn't come with a lock and so the hole for the lock in the handle had to be drilled out... don't try and knock the slug out... pot metal doesn't tolerate abuse well... and there is a little notch that needs to be cut out to accommodate the bar that keeps the lock stable, a metal file works great for this... and make sure the hole you drill is slightly, very slightly larger than the key hole housing or it won't turn once you install it. And then you need to drill a hole through the door so the lock mechanism bar has a space to slide through...A little work... but it does work! Whew!

It was the replacement of Schlage lock. I tried to replace and it was a tight fit and key would not turn. I tried several times and no luck. I would not recommend this product.

Dead simple to replace and old Schrader lock core. Rekeying could cost you $15 or putting in a replacement doorknob/deadbolt could cost $35+. Ease of installation: Took me about 5-8 minutes to replace the core myself with only screwdrivers. Functionality: Now I have a new key. Previous house owners never had one, apparently they only used the front door? 🤔🙄 Why did you pick this product vs others?: Because I only needed to replace the lock and not the whole brass door handle plate.

I’m conflicted because while the lock works out of the box as a door lock (most of you are probably buying it for a patio door) with no issues when using the provided key, the whole purpose of the manufacturer posting “Kwikset” in the title sets the expectation that it would work with Kwikset keys and thus conform to Kwikset specifications in addition to Weiser and Weslock which are also listed. As another reviewer mentioned, if you are planning to rekey this lock with Kwikset pins, I can confirm that Kwikset specification pins do bind the core. As I am not a professional locksmith, I’m not going to buy a variety set of pins so that I can have the necessary pin lengths to work with this off spec lock. As I needed to rekey this lock for a project of mine, I went ahead and filed down Kwikset pins and am now able to utilize the an original Kwikset key. For any homeowner wanting to use this lock with a Kwikset key, don’t waste your time trying to rekey this yourself, just buy the lock and pay a locksmith the few bucks to rekey it to whatever key you want.

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.

Ce produit étais pour un ami et ils étais très contant d'avoir ce produit. Ils la poser et tous va bien.

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.

Great product, installed very easily… so far it’s performed flawlessly….. highly recommended!

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!
