Post Key FOB issue

I had this issue sometime back but never got a chance to post it on the forum, not a regular user. I have a 2007 C280 4 matic.
My key fob works sometimes only with infra red. I showed it to the dealer & the performed SDS test. They also tested & inspected the locking system electronics. They recommended to replace either the rear glass with antenna amplifier or ream SAM module. What's the best way to deal with with situation. Most of the times it works, but it sucks when it doesn't because then I can't use my auto start with the key fob. Please suggest what I should do. Thanks in advance.

Both proposed repairs are quite expensive and if they are not certain which one will fix the problem there is no guarantee either will fix the problem.
