I have a 2001 e55. About 2 weeks ago my door locks stopped working and I can’t get into my trunk

Here are the symptoms

Key fob does not work door locks or trunk. Trunk switch in console does not work either

When I push the unlock button on fob my emergency blinkers go on and interior light goes on

Cars starts fine with the same fob so battery in car must be good

I removed the emergency key from the fob and it will not fit in the lock

Thanks in advance for your help
