Wow, thank you so much for photos, it's actually much smaller trim-job than I though! I'm guessing my little rotary tool would be inefficient here -- what did you use if you trimmed it yourself or did you have it done at the shop?

I've seen some cheap security systems which supposedly have immobilizer and the trunk release button on ebay. If I do install immobilizer I'll be saving about $120-$150 a year on insurance so I figured I better install the immobilizer than invest in remotes/new blanks.

Besides that there're two more gadgets I'm thinking of installing -- the TPMS (which I bought a few years ago for my landcruiser but ended up selling the truck before I installed TPMS) and the rear view cam/sensors. Last time I test-drove VX I forgot to take the measure -- what's the size of that insert in the rear door where JDM models have cam installed?

PS. At 25 bucks I think I better get the original remote just in case. Are the following the correct instructions for programming?

Open the driver’s door.

Insert key into ignition.

Turn the ignition switch to the ACC position and then to the LOCK position three times. (This step must be completed within 3 seconds – go as fast as yo can, or the system will not enter the programming mode.)

Within 10 seconds, close and open the door two times.

Turn the ignition switch to the ACC position and then to the LOCK position three times (again, do this within 3 seconds.)

Within 10 seconds, close and open the door. Verify that the power door locks cycle once to confirm that the system is in programming mode.

Within 20 seconds, press the LOCK button on the transmitter you are programming. Verify that the door locks cycle once.

Within 20 seconds, press the UNLOCK button on the transmitter. Verify that the door locks cycle once to confirm that the system has accepted the transmitter’s code.

Repeat steps 7 and 8 for each transmitter to be added.

Remove key from ignition.
