I just purchased a 2005 mpv with only one key and remote....after spending big bucks on new key and remote from dealer,,,i am now noticing that my original remote dies after 5 to 7 days ..and will work again with new battery but will not last .( chgd batt 3 times already....the key is ok to start the vehicle....has anyone ever purchased on e-bay those cheap uncut key and remote... do they work ? and wondering what is the programming method...dealer wants 65.00 for the key ,165.00 for the rmt..and 90.00 for programming plus more for cutting the key... also wondering if anyone can use their key to unlock the vehicle without setting off the alarm...I sure could use help on this ....thks mike
