Right, so my brother got this LS-S61 lock thing. Looks slick. Supposed to be great. Top rated smart locks, everyone says. But then he finds out… surprise! Not every door wants to play nice with these gadgety locks. Mine either. Learned the hard way. Ugh.
First big thing? Door thickness. These smart locks are fussy eaters. Your door can’t be too skinny or too beefy. Like, my back door? Thin like cardboard. Maybe 1.5 inches thick? Forget it. The lock mechanism pokes out funny, looks stupid, probably doesn’t lock right. The deadbolt bar thingy won’t reach far enough into the hole in the frame (that’s the strike plate, I think?). My front door is solid, old wood. Almost 2 inches thick? Closer to 2 and a quarter? That seemed okay… until we tried fitting it. Needed extra bits. Had to buy an extension kit separately. Total pain. Box didn’t mention needing extras! Probably should measure yours first. Get that tape measure!
Second? Material. Metal doors? Ahhh… tricky. Steel doors cause problems. Bluetooth signals get weak. Like your phone signal in a lift. So if your phone is in your pocket and the door’s thick steel, might not unlock. Standing in rain juggling groceries = annoying. Fiberglass doors are usually okay, they say. Wood is best? Mostly. Unless it’s warped. My dad’s shed door is warped wood. No smart lock survives that for long. Gets misaligned. Starts screaming error beeps. Then the batteries die faster.
Third? The DEADBOLT HOLE. Super important! Older houses? Watch out. That hole in the door edge where the deadbolt shoots out? Might be the wrong size. Needs to be exactly 1 inch wide? Or maybe height? I always mix it up. Height maybe? Whatever, measure the hole! If it’s small and weirdly shaped, you gotta drill it bigger. Made a huge mess of sawdust on my rug. Spouse was thrilled. Not.
And the strike plate! That metal plate on the door frame where the bolt goes. If it’s loose, or bent, or rusty… the bolt won’t slide in smooth. Jam city! Even the most expensive top rated smart locks rely on smooth bolt action. If your frame is rotten wood? Forget it. Needs replacing anyway. Security risk.
Weird edge cases? My friend has a door with rounded corners at the top where you mount the lock. The LS-S61 (or was it S60? They all look same) had this big rectangular backplate. Didn’t fit the curve! Stuck out like a sore thumb. He had to shave down the door edge. Looked… rough. Function over form, I guess.
Bottom line? Not all doors are smart-lock-ready. Check these BEFORE buying:
- Thickness: Like 1.75 to 2 inches is ideal. Thinner or thicker? Extra parts or pure headache.
- Material: Steel = Bluetooth issues sometimes. Warped wood = bad time.
- Deadbolt Hole: Right size? Probably needs 1-inch hole. Drill ready.
- Strike Plate: Secure? Aligned? Or the lock will fight you forever.
- Weird Shapes: Rounded tops? Unusual spacing? Good luck.
Spent like 3 hours on my brother’s installation. Was convinced I broke it twice. Turned out the thermostat needed batteries? Wait, no, that was unrelated. Anyway, it works. Mostly. Battery drains faster in cold? Maybe my imagination. Would I recommend it? Sure, if your door checks the boxes. Otherwise… maybe save money for pizza. Way less hassle. Good luck!
