Exterior keyed locks on Andersen gliding and hinged (inswing and outswing) patio doors open with a key from outside your home. Ordering a replacement key may vary depending on your patio door type and the number of keys you need.
How to Order Replacement Keys for Exterior Keyed Locks
Each exterior keyed lock on Andersen® gliding and hinged patio doors comes with a set of two (2) keys. If you lose one (1) or both, this article explains how to replace them.

This Article Will Help You:
- Replace one (1) key from a set for exterior keyed locks on gliding or hinged patio doors.
- Understand replacement options for a full set of keys. This depends on whether your patio door glides or hinges.
- Find more information on exterior keyed locks, rekeying doors, and replacement guides.
Let's Get Started
Replace One (1) Key from a Set
All Andersen® exterior keyed locks on gliding and hinged patio doors should come with a set of two (2) keys. If you have lost only one (1), Andersen® offers replacement blank keys 
for purchase online from the Andersen Parts Store. A locksmith or hardware store should then cut the blank keys correctly to match/copy the existing key.
Replace an Entire Set of Keys
For security reasons, we cannot replace an entire set of keys if it goes missing. We also cannot provide lock cylinders or keyed locks that match your existing exterior keyed lock. You can either replace the existing exterior keyed lock cylinder or order a new assembly. Ordering details vary depending on whether you have a gliding or a hinged patio door.
- If you have multiple patio doors that use the same key and an entire set of keys goes missing, all the exterior keyed lock cylinders or assemblies would have to be replaced.
