The FX projector is one of the smallest bi-x projector around, so I doubt any of the rear of the headlight needed trimming. Probably only the reflector itself was trimmed.
As soon as you "grab" the handle (as if to pull the door open), the rig unlocks. To lock, there is a small insignia on the top/front of the handle where you touch and it locks.
Is that what you meant?
If you aren't consdering lifting the rig, the xreas on the limited improves the handling over the sr5. If you don't like the 20's, you can easily find a buyer for them.
As started, the heated seats are wonderful :)
I use button #1 on a Raynor garage door and I get almost 1/2 block range. I do have to hold it down for about a sec though (I initially thought it didn't work until I held it down).
