※ Please refrain from price negotiations. ※ Purchases without comments are welcome. This is a KABA model 4037 key cylinder, a standard for dimple keys. It comes with all four dimple keys. I purchased it at Tokyu Hands over a decade ago and used it for pick-resistant security on my front door. I am selling it because I no longer need it due to moving. This cylinder has a high security level, making it difficult to duplicate keys. It is still fully functional, so if you need one, please consider it. Please consider only if you understand that this is a used item. Returns are not accepted after purchase. Thank you for your understanding. #dormakaba #dormakaba
