A small issue we have is that our 2009 ES350 and 2010 RX350 have the same key fob design. They are identical. So of course, even though they are attached to different keys, we would get them confused. So, we differentiate them this years ago by purchasing a colored leather key fob "glove" (I don't know what else to call it) at the dealer. So, our RX is white and ES is "brown/grey" something or other. It's a Pebble Beach Edition so the exact color name escapes me know. Anyway, a white "glove" for the white RX and a grey "glove" for the ES. After years of use, the covers are completely worn and discolored. These covers are no longer available so I took to ebay/aliexpress to find replacements. I found these (link below). These are not silicone or leather, they are plastic. Seems to be durable and the transparent part where you can press the fob buttons are of a very thin clear plastic or film. I can see this getting damaged or worn out, but I believe it will be fine. I'll report back if any issues.

Completely worn out.




New cover unboxing.





Test Fit because the cover seemed way too large, but the fob fit perfectly inside.



Some assembly required. Tools were included.


Amazingly, I don't have a picture of it all snapped together with keys, etc. Anyway, this cover was very well made and recommend it to anyone looking for something like this. I paid $21 or 23 including shipping. I want to say it took about 3 weeks for it to come in. Very happy with it. For my ES, I ordered a black as gray isn't available. Like I mentioned, I'll report back with any issues. Feel free to ask me anything about this product.

Thought I would share, happy motoring!

Edit: resized the photos.

 

My wife and I have one Lexus. We each took a key fob when new.
It is her car and I drive it maybe once a week.
I noticed the other day that her fob cover still looks like new while mine was heavily worn.
Hers has ridden in a purse for seven years on a nine pound ball of tangled good luck charms.
Mine was in and out of a pants pocket.
This tells me I've either got to give up the skinny jeans or carry a purse.

 

I rarely drive my wife's 2015 RX350 (maybe twice a month) so I do not carry my fob for that vehicle on my key chain. It stays on a bookshelf hook in my home office until I need it. As a result, that fob glove still looks brand new.

 

On my 2019 I had a really cool looking carbon fiber shell case. It looked good but killed my range, I had auto start and it dwindled the range by about half. It still looked good enough that I kept it. My 2010 one of em had the leather case still brand new which was probably the previous owners spare. I’m not to crazy about it but it lives in my pocket so even as ocd as I am I really don’t think twice about the remote.

 

I want one in white!!!
