Keyless (touch) entry on 17’ SR5?

Are the SR5's able to have the touch-sensitive unlocking added?

Thanks all,

 

Lock your truck. Walk up to the drive door. Grab the handle. If it unlocks you have it. If it doesn't you don't.

 

... Does your key have a lock/unlock button?

 

Haha, yes.. My apologies. I'm talking about touch-sensitive unlocking. That's one of the features I know the TRD's have but I'm wondering if the SR5's have the capability to add it.

 

I'm sure you could add it with some money down on the table but I don't believe it is a factory option. The factory system has two bumps on the door-handle that you would notice. An aftermarket system(Dont know if any are made for this truck) you would probably have to take a look at the fuseblock to see if it looks like someone tampered with it to add something.
