Is there an easier way to do this?
You don't need new keys, they will still work, remember you are only replacing the remote keyless function here.

The absolutely cheapest way to do this is get the legacy keyless, one used legacy key, a new housing/blade, and one used old legacy teardrop fob. Swap the keyless units, make your all in one key by hacking the valet key for the transponder, and program the old used legacy teardrop for use with the other stock keys. When done you now have one cool key, a remote and key set, and a spare key. You could even sell your impress keyless unit and remotes on eBay..
