so ive recently gotten a '15 C300 and it didn't come with the start/stop engine button so I went on Amazon to buy the button

i put the button on and i was able to start stop the engine just fine

the problem is when i leave the car and try to lock the car w my keyfob it doesnt even go thru

so to lock my car i have to take the button off and put in the fob and take it off

anyone know what i should do to fix this
