Two general questions about my jeep

I have a 2007 WK 4x4, my first question is this, when I purchased it the previous owner only had one key for it, if I were to go to walmart and have another key made there would that work to start my engine or is there an anti theft chip or something in the original keys? Could a replicated cut key at LEAST unlock my door?
2nd question is, if I take off the little air dam on the bottom of my front bumper to gain a little ground clearance in the front will it noticeably affect my gas mileage? Thanks for your time.

If you get a key cut at WalMart then only use it to open the doors, it won't start it.


if you remove the lower air dam it should increase your mpg by 1 maybe?

This is the full key you will need to unlock and start the car. A standard "Walmart" key will just unlock the doors.http://www.amazon.com/dp/B00DP3DGR8/...I1TKH0MJKZ3DBL

Yes it will by a surprising margin. Sometimes up to 5 mpg but it's probably more like 2-3.

So when you say it could change by up to 5 mpg you do mean that it could get up to 5mpg less, meaning WORSE gas mileage right?

You will get a bit better mileage with the lower deflector in place but its real easy to pull off and put back on when needed.

You need two keys to program additional keys into your vehicle. If you don't have two keys, then you can either buy one online and take it to a dealer/locksmith for programming, or buy one from a locksmith/dealer and have them program it for you all in one shot.
