I bought all my hardware for my new house from Emtek. It is over the limited warranty, but I contacted them when everything was still under warranty. One very expensive Electronic Handle has never worked and I've had multiple installers out to try and fix. Emtek will not help at all, even though I have had this trouble from beginning and was in touch with them a couple of years ago. Spoke to someone at Emtek who basically told me I am out of luck, the item is discontinued, and a replacement would be more than double what I paid for it 5 years ago. I will NEVER buy or recommend Emtek again!
