hello and thank you for replying so quickly

i am still having a problem with reseting my wrench light

what position is the smartkey in? metal piece up/down

what do i hold for 15 sec the unlock, lock or truck icon


again thank you for all your help


i don't have an owner's manual - thankyou again

Benzmac previously stated:

"It is spelled out in the owners manual!
1) key off, all doors closed.
2) key on, push button two times.
3) key off, push and hold button and turn key on , wait 15 seconds."

He does not mean the unlock or trunk switch! It's one of the button ons on the instrument cluster. Not sure which one, I think maybe O or R, which ever yours may be.

Good luck.

And you should invest in an owner's manual! They are only $10 and WELL-WORTH IT.
