How to Find Your House Key Code

The location of the key code depends on your lock type. For Yale-type cylinder keys, look at the flat side of the key blade near the shoulder — you will see a short alphanumeric code such as KA1, YA51, or 1A1. For UPVC window keys, the code is typically stamped on the key bow or printed on the lock face. For mortice keys, check the bow (the part you hold) for a stamped number. For padlock keys, the code is usually on the bottom of the padlock body or on the original key blade.

If you cannot find your code, use our key code locator tool on the homepage for a step-by-step visual guide. Alternatively, send us a photo of your key or lock and our team will identify the correct replacement for you — free of charge.
