The lock is great! But I purchased a version without the sensor. Can I purchase the sensor separately or do I need to purchase a different version of the lock? ---

@Robertson1 The [**Door Sensor**](https://support.u-tec.com/hc/en-us/articles/360060210251) is **only** for **U-Bolt WiFi / U-Bolt Pro WiFi and U-Bolt Z-Wave / U-Bolt Pro Z-Wave** , which can detect your door’s status if you paired it correctly. U-Bolt Pro can not work with the Door Sensor. You can click [Compare – U-tec (](https://store.u-tec.com/pages/compare)[u-tec.com](http://u-tec.com)[)](https://store.u-tec.com/pages/compare) or see below to find the main difference between U-Bolt Z-Wave / U-Bolt Pro Z-Wave, U-Bolt WiFi / U-Bolt Pro WiFi, and U-Bolt / U-Bolt Pro: | Model | Fingerprint | Bluetooth | WiFi | Z-wave | Door Sensor | | --- | --- | --- | --- | --- | --- | | U-Bolt | ✖ | ✔ | Ultraloq Bridge is required. | ✖ | ✖ | | U-Bolt Pro | ✔ | ✔ | Ultraloq Bridge is required. | ✖ | ✖ | | U-Bolt WiFi | ✖ | ✔ | Built-in WiFi chip integrated. | ✖ | ✔ | | U-Bolt Pro WiFi | ✔ | ✔ | Built-in WiFi chip integrated. | ✖ | ✔ | | U-Bolt Z-Wave | ✖ | ✔ | Ultraloq Bridge is required. | Z-Wave Hub is required. | ✔ | | U-Bolt Pro Z-Wave | ✔ | ✔ | Ultraloq Bridge is required. | Z-Wave Hub is required. | ✔ | I hope it helps.

I did not order the model that has door sensor capabilities however my daughter did and asked me to install the unit for her. I was really annoyed that it does not work on metal doors. My daughters door is metal so it is non functional, my doors are metal and so are 99% of all new doors installed today. The only house I know of is my dads which was built in the early 60’s that has a wooden door mainly because steel doors did not exist back then. This should be clearly indicated in the specs so all are aware a wood or fibreglass or non magnetic metal door such as aluminum are the only doors this door sensor will work with. I suspect many have been disappointed find out about this after purchase. ---

I echo that. I’m really annoyed about it. We got it specifically to be able to keep an eye on it.
