The full dimensions of the lock are: 5.6” (H) x 2.6” (W) x 1.6” (D). ## Can I use antibacterial wipes or spray to disinfect my Yale Approach? Yes, you can clean your Yale Approach with alcohol-based sanitizing wipes or spray. Please avoid using petroleum-based products, such as acetone, to clean your Yale Approach. ## What is the Expected Smart Lock Battery Life?  The battery life for the Yale Approach is 12 months, depending on use. ## How will I know if the batteries in my Yale Approach need to be replaced? Once a lock’s batteries reach 25% capacity, a low-battery notification appears on your phone’s unlock screen. You may wish to replace the batteries when you see this notification. If you don’t replace the batteries at this time, you will begin receiving daily emails and push notifications as the batteries approach the end of their life. ## How do I change the Lock sound? It is not possible to change the sounds a Yale Approach makes. If you would prefer your lock make no noise, you can turn the sound off in the Yale Access app: 1. In the Yale Access app, tap the **gear icon (⚙️)** to access **Lock Settings.** 2. Tap your Yale Approach lock. 3. Toggle Lock Sounds **OFF**. ❗ **_You must be within Bluetooth range of the lock to modify this setting._** ## What do I do if lock sounds are enabled and the lock stops making sounds? If lock sounds are enabled in the Settings menu, but the lock is not producing sound, rebooting the device may help. To reboot the lock, remove one battery and replace it. In most cases, the lock sounds will return after taking this action. ## Are Yale Approach locks weatherproof? The Yale Approach smart lock is intended to be used on the inside of a door and is not designed to be weatherproof. Please review the following specifications for details.  Environmental Specifications: * Operating Temperatures: 32-104F (0 to 40C) * Storage Temperatures: -4 to 158F (-20 to 70C) * Operating Humidity: 10 to 85% Non condensing * Storage Humidity: 5 to 90% ## What do I do if the Yale Access app says the lock is unlocked when it's actually locked? 💡 **_Have you installed your lock?_** Incorrect lock status may occur if the lock is laying on a flat surface. If the Yale Access app shows that your lock is locked when it's really unlocked (and vice versa), chances are it needs to be recalibrated. Recalibration is necessary if the lock stops operating as it should. For example, if the lock circle displays as green when the door is actually locked, recalibration is needed and should fix the issue. Before proceeding with the recalibration steps, remove the lock's battery cover and remove and reinsert one battery. Next, while you are within Bluetooth range of your lock, follow the steps to recalibrate: 1. In the Yale Access app, tap the **gear icon (⚙️)** to access **Lock Settings**. 2. Scroll down and tap on Calibrate Lock. 3. Follow the in-app instructions to recalibrate your lock. ## What do I do if my guest does not receive the invite I sent? If you sent an invite to your lock and your guest does not receive it, there may be an issue with the contact information you sent it to.  Double check that the number you sent the invitation to is the correct number.  If the invite was sent to an incorrect number, go into the Yale Access app and delete and resend the invite ensuring that the phone number is correct. ## What do I do if my guest received the SMS invitation, but my key does not appear in their keychain? If your guest received an SMS invitation from you, but they do not see your key in their keychain after setting up their account, there may be an inconsistency between the number you sent the invite to and the number the guest created their account with.  If this happens, ensure that the numbers match by cross-referencing the number you sent the invite to with the one on the new account.  If the numbers do not match, delete the invitation and resend it to the number in their account. The Guest should find the key in the keychain after completing this step. ## Is the Yale Approach Lock compatible with double-cylinder deadbolts? The Yale Approach Lock is compatible with single-cylinder deadbolts at this time.  If you can use a physical key to unlock your door from both sides, you likely have a double-cylinder deadbolt. Visit the deadbolt compatibility article for a comprehensive list of compatible deadbolts.  ![](https://cdn.prod2.kustomerhostedcontent.com/media/5f6cab56313fd9001af97923/32a384e87b27ba86176f6307648355a9.png) ## How many properties and devices can I have attached to my account?
