Tacoma Homekit Integration/Automation?

I haven't seen anything like this on the site but I am not sure how to ask the question either. I would like to have something in my truck that would automatically lock the doors at a certain time each evening. I have explored Carlink and Drone Mobile X1 but I don't want to pay for a subscription to do this. This would just be something that I would use at home within the range of my home WiFi. Has anyone heard of a piece of hardware that might accomplish this?

Thanks in advance!

 

I just use my keyfob when I get out. Then it does not matter of a certain time or location or anything else.
