Anderson Door - Lock Not Working

Thanks in advance for any advice provided.

The lock on my Anderson hinged patio doors no longer works.

It is brass hardware and the small knob that you turn to lock or unlock the door now spins without engaging the lock.

This happened out of the blue; the lock has always worked great.

Anyone have experience with this?

Many thanks.

How old? Andersen warrants the hardware for 10 yrs I believe. Something may have just broken or stripped on the lock actuator. You'll have to take it apart to find out, but all that takes is an allen wrench for the handles and a phillips screwdriver.

There are instructions at the Andersen website....Andersen Windows and Patio Doors | New Construction Patio Doors | Replacement Patio Doors | Energy Efficient Patio Doors

Check the active hardware installation PDF

If the key also just spins without engaging the lock, you have a broken cam. You will need a new cylinder.

Are the hinge screws coming loose? How have you been re-aligning the door in the past? You can check a website I found online. Good luck.

same problem

I just discovered I am having the same problem with my Andersen door as well. I don't have the french door, just the single pane door going from my mudroom to my deck. The knob just spins and doesn't engage the center bolt.

I bought the house about two months ago so I don't have any original paperwork, no idea who put it in or where to go for replacement parts. The door was probably installed between 2000 and 2002. Also, we have no key for the door so I can't test to see if it locks from the exterior. Had a locksmith come out when we first moved in to change all the locks but he said he wasn't sure on how to change this lock.

Have you had any success in fixing your door?

This just happened to my outswing patio door. It was an easy fix. Remove the interior eustucion plate with a screwdriver and 1/8 inch hex key to remove the door handle. The plate comes off revealing that the lock knob is merely slotted to a square rod. In my case this one inch-long square rod had slipped forward and was no longer engaging the locking mechanism. Pull the 1 inch rod out and firmly reseat it back in on it's mounting rod end. My rod had slipped out and was not engaging the lock cam on the inner mechanism. Confirm that the lock rod engages the cam and then carefully put the plates and door knob back on the lock.
