If your Andersen door lock isn’t working properly, there are a few steps you can take to try to resolve the issue:

  1. Check the Key: Try using a different key if the key isn’t turning in the lock. Your key could be worn or bent, preventing it from properly engaging the lock mechanism.
  2. Lubricate the Lock: If the lock feels stiff or the key won’t turn easily, the lock might need lubrication. Use a graphite-based lubricant, which is appropriate for locks, to lubricate the lock cylinder.
  3. Check the Alignment: If the door isn’t aligned correctly with the jamb, it can prevent the lock from engaging. Make sure the door is hanging evenly and that it closes without sticking.
  4. Check the Latch and Strike Plate: If the door doesn’t stay closed, the latch and the strike plate (the metal plate on the door frame that the latch engages with) might not be aligned. If they’re misaligned, you’ll need to adjust the position of the strike plate.
  5. Inspect the Lock Mechanism: If you’re comfortable doing so, you might need to remove the lock from the door to inspect it for damage or wear. This typically involves unscrewing the lock from the door. If you notice any broken or worn parts, you’ll likely need to replace them.
  6. Contact a Professional: If the above steps don’t resolve the issue or you are uncomfortable performing them yourself, it’s best to contact a professional. A locksmith can often repair or replace a faulty lock. Alternatively, you can contact Andersen’s customer service for help.

Remember always to exercise caution when working with locks and doors. If you’re unsure about something, it’s better to seek professional help than risk damaging your door or lock.

Andersen door lock latch is stuck

Precise Andersen Door Lock Problems and Troubleshooting Guide 1

If the lock latch stuck on your hinged patio door, whether an inswing or outswing model, is stuck and not moving, follow these instructions for either new patio door units or units where the lock latch was previously functional but has stopped working.

For New Hinged Patio Door Units

Start by inspecting the lock latch. It should be removed if you find a white plastic component between the lock latch and the mechanism. This piece is included to prevent damage to the lock and patio door panel during transport and installation.

To carry out this task, you’ll need:

  • Safety Glasses
  • Flat Head Screwdriver

Use your flathead screwdriver to pry out the plastic component. Once removed, the lock latch should spring outwards. If the plastic part is absent or the lock latch doesn’t move after removal, move on to the next section.

For Units Where The Lock Latch Previously Worked But Has Now Stopped

If the lock latch has ceased functioning, it may have been pushed too far in, causing it to jam within the lock mechanism.

To fix this issue, you’ll need to refer to the “Changing Hinged Patio Door Lock Mechanism Handing” section in the “Handing of Lock on Hinged Patio Door” guide. Follow the instructions provided there to free the lock latch. Once released, push it back into its correct position, careful not to alter the handing.

If the lock latch remains stuck after following the guide, replacing the entire lock mechanism might be necessary.

Andersen door lock handle is stuck in the up position and completely locked.

The Andersen door lock handle is stuck in the up position and completely locked.

If the handle on your Andersen door lock is stuck in the up position and the door is locked, there’s likely a problem with the internal lock mechanism. Here are some steps you can take:

  1. Attempt to Unlock the Door: Even though the handle is stuck in the up position, try using your key to unlock the door. Sometimes, this can realign the internal parts of the lock and allow you to lower the handle.
  2. Lubricate the Lock Mechanism: The lock mechanism might need lubrication if the key turns, but the handle remains stuck. Use a graphite-based lubricant and apply it to the keyhole. Then, try turning the key and moving the handle again.
  3. Inspect the Lock Mechanism: If the handle is still stuck in the up position, you may need to remove it to inspect the lock mechanism. This typically involves unscrewing the handle from the door and carefully removing it to avoid damaging the internal parts.
  4. Replace the Handle or Lock Mechanism: If the internal parts of the lock mechanism are broken or worn, they might need to be replaced. Depending on your comfort level with DIY projects and the specific model of your Andersen door, you might be able to replace these parts yourself, or you might need to hire a professional.

Andersen Sliding Door Lock Not Working

Andersen Sliding Door Lock Not Working

It sounds like you’re looking for advice on troubleshooting and fixing a sliding door lock from Andersen that isn’t working properly. Let’s go through your list in a more detailed manner:

  1. Fix Alignment with Latch: Over time, the door can shift slightly, causing the latch to not align properly with the strike plate on the door frame. If this is the issue, you may need to adjust the door or the strike plate to correct the alignment.
  2. Tighten Up Screws: Check all the screws in the door and lock mechanism. Loose screws can cause the lock to work improperly. Be careful not to overtighten; this could strip the screw holes or warp the lock mechanism.
  3. Clean Up The Unit: Dust, dirt, and grime can accumulate inside the lock mechanism and prevent it from functioning properly. Use a can of compressed air to blow out any debris. You may need to disassemble the lock to clean it more thoroughly.
  4. Adjust the Height Of The Rollers: If the rollers are too high or too low, the door may not align properly with the latch. Adjust the height of the rollers as necessary to ensure proper alignment.
  5. Use Lubrication: The lock mechanism may be sticking due to lacking lubrication. Use a silicone-based lubricant on the lock mechanism and keyhole. Avoid petroleum-based lubricants, as they can attract dust and grime.
  6. Check for Warping Issues: If the door or frame has warped due to moisture or heat, this could cause the lock not to function properly. If you notice any warping, you may need to replace the door or frame.
  7. Get A Replacement: If none of the above steps work, the lock mechanism may be faulty. In this case, you’ll need to replace the lock. Replacement parts can typically be ordered directly from Andersen.
  8. Call A Locksmith: If you’re uncomfortable doing this work yourself, or if the problem persists after trying the above steps, it may be best to call a professional locksmith. They have the knowledge and tools necessary to diagnose and fix the problem.

The key Won’t Turn in Andersen’s door lock.

If the key doesn’t turn in the lock, it could be due to a misaligned lock, a worn-out key, or an issue inside the lock cylinder.

  • Check if the key is the issue by trying another key if one is available.
  • If the problem persists, apply a graphite-based lubricant to the key and insert it into the lock.

The lock Doesn't Latch Properly

If the door doesn’t stay closed or the lock doesn’t engage, the latch and the strike plate might be misaligned.

  • Check if the latch and the strike plate are aligned. The latch should easily enter the hole in the strike plate when the door is closed.
  • If they are misaligned, try adjusting the position of the strike plate by loosening its screws, realigning it, and then tightening the screws.
  • If the door itself is misaligned, it might need adjustment. This could involve adjusting the door hinges or the door installation.

Difficulty Locking or Unlocking

If you’re having trouble locking or unlocking the door, it could be due to a misaligned door or an issue with the lock mechanism.

  • Check the door alignment. It might need realignment if the door sticks or doesn’t hang evenly.
  • If the door is aligned, but the lock is still difficult to operate, lubricate the lock cylinder with a graphite-based lubricant.

  • If the lock is stiff but not frozen, it may need lubrication. Use a graphite-based lubricant, which is suitable for locks, to lubricate the lock cylinder.

Andersen Keyless Entry Not Working

If your Andersen door has a keyless entry system and it’s not working, first check the batteries and replace them if needed.

  • Check the batteries in the keyless entry device and replace them if necessary.

  • If the problem persists, the electronic mechanism might have an issue, and professional help may be needed.
