ML 350
Key no longer detected!

I have a 2011 ML350 (This is not a fob battery issue)
Anyone else have a similar issue? Let me know if so and cost of repair. Should I be concerned that a series of other electrical problems are on the horizon???

My car will no longer detect my key. For example, the door will not open if the fob is on me. I must manually press the unlock and lock button to unlock and lock the car. Secondly, my car will no longer start with the keys anyplace inside the car. The car will only start if the actual key is turned inside of the ignition (found under the push button start).

Easy! Stay cool! Could be just an drained battery.
