## Questions & Answers

**Q: Can I swap the top shell to my original Chrysler shell? I have an button broke .**
A: There is a very small size difference in casting size. The old top will be a loose fit in the new bottom and a new top (button side) is not likely to snap in a old bottom. I wanted to do this as I wanted to keep the old bottom as it was in great shape and has the Dodge logo. My existing old top piece is in terrible shape. 

Ultimately I just I used both new halves. The logo is not that important to me. A working device is.

**Q: en la ranura de esta carcasa cabe mi llave original de Dodge Journey?**
A: Perfectamente

**Q: I have a key and fob it all works but I want my car to turn on from outside can I just put my key and will it turn my car on ?**
A: Sounds like you want a remote starter for your car. This product covers your key fob and thats it.

**Q: Can I swap the internals from my working key fob to this fob? The key ring part on my key broke on my key fob and now I cannot attach my keys to it.**
A: Yes, this item is a key case,  NO interior (remote/electronics/transponder chips) unit inside. Thanks!
