    I've had my 2018 Tundra about 5 1/2 years and lately the remote lock/unlock seemed sluggish so I figured it was time to put a new battery in it.

    There is a notch on the edge to be used for popping open the shell so while I was in a store next to the battery display I took out my Swiss army knife and popped it open. It came apart, all the buttons fell out all over the floor (i had to crawl around to find them all).

    But there is a "module" that looks to be very solid and difficult to open to get to the battery. I put the parts in my pocket and used my spare key to get home.

    Once home, I took a close look and couldn't really see an easy way to get this open, it looked like it was designed to discourage this actually.

    Anybody changed the battery in their keys? If so, should I just take it to the next level and pry the internal module open?

    To add to this, I got the battery changed in both of my keys yesterday (thanks very much for showing me the video, this was very helpful). The "USE COIN TO OPEN" instruction on my key module was almost impossible to find and read, very tiny and I had to hold it in a certain angle to actually see and read it (with my 73 year old eyes).

    One thing I would recommend when watching the video is to NOT touch any of the contacts with your fingers. Also, wipe the new battery clean with a tissue to remove all finger oils. Reliable contact could be compromised if this is not done (I've run into this many times in the past).

    Also, I take a sharp awl (in my case carbide tipped) and scratch CR2016 on the case so I know which battery to buy the next time.
