No, I don't "super lock" on a regular basis (only if I know the car will be sitting idle for more than a week).
I do, however, regularly switch off the key fob (you can do this by pressing both buttons for about three seconds until the red LED flashes twice).
This keeps the key fob from transmitting any signals until you press any key again.
You cannot unlock the car with a thusly disabled key fob (and I think it may prolong the key fob's battery life at the same time) - wow! another 50ç saved!

Moreover, I keep the key fob in a padded
old Smint box which fits it perfectly and prevents from inadvertent key presses (which would reactivate the transmitter) plus is capable of shielding even an active key fob!
The current Smint box is somewhat longer, wider and flater but is still capable of holding (and shielding!) a Honda key fob but it will need different padding.
