I like Mercedes remotes better...when u press the "lock" button one time...lights flash 3 times...to tell u its lock. and when u press it again..it repeats. BUT for BMWs..they flash ONCE and thats it..u can press the "lock" button as many times as u want but u wont be able to tell from a far distance if ur car has been locked or not if u missed the initial flash..u still with me???

just my 2 cents.
