Yes, Schlage and Dexter have the same keyway so the keys are interchangeable.
First you need to get your key code off of your original Schlage key with a number stamped on it. It’s a 5 digit number like 54854.
After you put your new Dexter Deadbolt in your cart you can give us special instructions when viewing your cart contents. Put the key code in there like this.
Please key all locks to 54854
There is no charge for keying.
