Default so I went to replace key fob battery

The first key battery replacement worked like a charm. However on the second key I notice the two tiny tabs that hold battery in place are missing. The key still works but it isn't ideal as battery isn't secured. Has anyone experience this issue? What did you do? Ordered a new case and transfer all internals over? If you did, where did you buy the replacement?

red circles or blue? If they snapped I would take a felt or small dot like what you use on cabinets to soften their closure. Place it on the opposite side where the red dot is. Or any thin item that will stick. Otherwise a new fob is an expensive alternative. Did you use the edge of the internal key to pop open the fob and to pop out the battery?

The case is fine, the battery section is attached to the internals which just pops out of the housing.

tiny tabs you circled in blue are missing. They are there in the first key. I had the video up and followed along just in case.

yeah, the tabs circled in blue appear to be the larger more rigid of the 4 tabs. I’m not sure what you mean about the video. Unless you are referring to like a “how to” on changing the battery. The battery and transmitter are housed in a rubber casing and pop out separately. If you want a transmitter that has all four intact plastic latches for the battery, it looks like buying a whole new fob would be the only cost effective way. But I would personally try my suggestion first to avoid that cost. Someone else may have a better solution. Good luck.

Not that this helps your situation now, but I take the key edge (circled in green) and place in between the smaller tabs ( circled in red) and pop it out. Not sure which way you did but they all appear delicate to a certain degree.

The housing (shell) is about $15 and the key fob in total is about $210. Not sure of Lexus pricing. This is for 2019 hybrid. YMMV and it's probable to find it cheaper elsewhere. This is just what I happened to find. The company doesn't cut or program the keys so a dealer or car locksmith would be needed.

Secure it with some small tape. It works so I wouldn't worry about it.

Here is the example of what I would use if this was my situation. The more flat type of bumper would be best. Felt would work too. May have to adjust until it fits. Tape could be used but might be more difficult to work with considering there is rubber housing and the opposite side is where the buttons are depressed. Either way much cheaper than a new unit.

Beautiful solution as well.

Took apart my key to check it out. I'd go with the above suggestion of the rubber. There seems to be a perfect little spot for it within the circle opposing the battery. also the key has a similar rubber pad next to it for what i assume is an electronic chip. so same concept.

honestly just stack little cut squares of electrical tape (or similar squishy stuff). It should hold.

there's probably a ton of stuff in the house you could use.

this would work too: https://sugru.com/buy/sugru-mouldabl...RoCDoYQAvD_BwE

That actually looks handy. I'll likely pick some up for myself from amazon.
