Ultimate Convenience: SL-591 Car Window Punch Button Lock Box
I recently bought the SL-591 Car Window Punch Button Lock Box because I needed my Turo customers to access the vehicle on demand without me being there to hand over the keys. This lockbox has been a game changer! It's super easy to install on my car window and has enough space to stash the keys and even the car fob. The punch button keypad is a breeze to use—no more fumbling with tiny dials or keys. It’s like texting on an old-school phone, but for your car keys. What I love most is the peace of mind it gives me. The solid metal construction feels really secure, and the protective rubber cover keeps the keypad safe from the elements. It automatically locks when I close it, so I never have to worry about whether it's secure. Plus, I can easily change the combination if needed. Now, instead of awkwardly waiting around, I can just give my Turo customers the code and let them get on with their day. Whether you’re into car sharing, running, or just need a hands-free solution, this lockbox is a must-have. It’s tough, reliable, and incredibly convenient—highly recommend!

Works as intended
This box does what it's supposed to. I needed a way to store my key safely within close proximity of my car in public, but not on me, and this does the trick. To my surprise there is no "under the car magnetic box with a combination lock", which would be perfect (maybe I'll build my own, but that is a story for another day). This is as close as it gets. There are 2048 possible combinations, I would prefer 4 10-digit dials (10000 combinations) but eh, 2048 is fine as my car is parked in a crowded place (someone breaking the window to steal the box is unlikely) and I can see it pretty much at all times. The box itself is very sturdy, made of metal except for the cover flap which is hard plastic. It's quite heavy and there's plenty of room in there for big car keys. A minor inconvenience is that you need to punch in your combination both for opening the box AND closing the box. Not a huge deal. So far I'm happy with this box.

Great for Turo host and guest
Easy to use, fits well on windows. Bought to use for turo and it is easy for the guest to use as well. It is affordable, have bought multiple times due to customers trying to install incorrectly and them breaking.

Works well!
Perfect! I rent a vehicle on Turo and this is exactly what I needed. I do not have to be present when my client comes for the vehicle. Great buy!

The best lockbox
The best lockbox. I’ve ordered so many different lockbox brands for Turo and this is the only one that fits the key with a signal blocking pouch.

One out of four purchased failed
I purchased four lockbox’s but after a week, the push buttons do not work on one of the locks. No other issues besides that and they are easy to use. If you’re looking for long term use, I would spend a bit more and get a better quality lock box.

Keypad broken within two weeks
The keypad was broken within two weeks of use. Unfortunately, I didn’t catch it in time to return the item. Also, I discovered this item does not block the RFID for key fobs. So the fob can be locked in the lock box, but thieves can still unlock the car because it’s not blocking the signal. Not good for Turo or rentals.
