In the process of ending our key fob woes, I decided to test out a few key fob covers from AliExpress. There are tons of them out there and few of them looked up to snuff. I will try not to get too detailed here but I will include some of my own pictures, thoughts, and the links to purchase.
Silicone Sleeve & Soft Touch Plastic Cover - $6.69
Positives
Cheap
Great overall fit and finish
Makes finding the lock button a cinch
Soft touch material is very nice in the hand
I used it for about a week with no accidental alarm presses
Negatives
Kinda bulky
The soft touch material and silicone is a bit grabby in the pocket
Since the alarm button is still flush with the rest of the cover, I am still a tad apprehensive

Wood Cover - $35.99
Positives
Good fit and finish
Unique look and feel
Securely holds fob in place
Slides in and out of pocket easily
Has the highest raised edges to prevent accidental alarm presses
Negatives
Cost
Bulky
Area below alarm button is not covered by the wood

Aluminum Alloy Cover - $14.92
Positives
Slim
Raised edges
Reasonable price
Most inconspicuous
Slides in and out of pocket easily
Good fit and finish with included foam pads
Weight of aluminum provides a premium feel
No accidental alarm presses since it's been installed (2 months and counting)
Negatives
The coating can chip/mar, showing the bare aluminum
Rough/noisy on other surfaces (counter, pocket items, car interior depending on where it's placed)

I have used them all for at least a week or two and
I like the aluminum cover the most. The biggest con I see is the covers must be disassembled using a small Phillips screwdriver. Not an issue most of the time, but could be if the manual key is needed and no screwdriver is handy.
Lastly, for being Grade A Chinesium, I am impressed with the quality of all three. The lanyards/key rings they come with are garbage however. A screwdriver was included with each cover. Hope this helps!
