Review: Perfect shell, amazing price. That’s great value. - This Key Fob shell worked perfectly for my 2008 Prius, works the exact same as my original fob before I replaced the shell, even fits perfectly into the insert slot in the Prius! All lock buttons continue to have full functionality. I also carved out a recessed spot to glue in the old Toyota logo (not required for use, just a fun touch- does require substantial effort to do so) This fob is built very durably, I dropped it while putting it together and no issues whatsoever. It looks clean and fresh. The shipping was super fast as well. When transferring the innards of the old fob, be sure to transfer the chip, circuit board, battery, the rubber seal from battery opening, and physical key. If you’re unsure of how to do any of this, go ahead and watch a video on YouTube, there are plenty. Also you’ll have to physically break open your OEM key fob in order to access the parts since the original’s halves are glued together. Also I’d recommend adding a little piece of the plastic bag to the corner where the light is in the corner to block the hole from dust and grime.
Review: Great replacement - Works perfectly . Very happy

## Questions & Answers

**Q: Will it works same as my old FOB did if only take all the parts out of my old FOB and put them in this one?**
A: Yes. It will do nothing different than what your old FOB did but look brand new.

**Q: What if the key shells don't snap together when installing?**
A: Key shell installation requires placing the internals in the correct position, then aligning the two parts, snapping one side first, then the other. Fastening on both sides at the same time is likely to fail to install successfully .

**Q: What should I do if the button signal is not sensitive after the key case is installed?**
A: It is possible that the chip is not installed tightly enough to cause poor contact. It only needs to be reinstalled to align the internal components with the contacts on the button and fix it.

**Q: Does this key fob case include screw parts?**
A: This key contains 4 small screws. If you have received a product with missing parts, please request a replacement directly.
