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 hangs evenly and 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. 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.

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, 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.

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. Apply a graphite-based lubricant 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.

Conclusion

In conclusion, even though Andersen door locks are among the most reliable, they are not immune to problems. Understanding these potential issues and knowing how to handle them can make all the difference in ensuring the security of your home.

Remember, if your Andersen door lock problem persists despite your best efforts, don’t hesitate to contact a professional locksmith or Andersen’s customer service for further assistance.
