Q: Can you install this if your car doesn't have a key fob just a single key to start n lock the door?
A: undefined
Q: Do the Viper Keyfobs replace the OEM Keyfobs?
A: No they do not if your fob is factory. Which i like which is also why i bought the one thats the exact same with a 1 button Fob to start engine.. Open and close doors. But maintaining your fob the rest is not need. You want to unlock your car with your fob if you autostart. If not and do it by hand etc your car will auto cut off.. The less button viper is a $100 cheaper.

Had to get a new remote start in my new car I love it! Just stating it with a press of a button makes it so much easier when it’s cold outside and I have to let my car heat up in the winter. And it comes with two I love it! Thank you Best Buy!!

This is my second Viper remote start system. This particular version works great just like the first. Two issues with this one. It doesn't have pit stop mode and my hazard lights are flashing when utilizing remote start. Im just trying to warm my car up, i don't need to look like im in need of assistance. That's a bit annoying, but other than that it works fine.
