Would standalone setup cause OEM fob to lose range or not work

Question

Hello, installed a 3x lock setup into a 2015 VW Jetta, auto, gas, key start. Used an EVO ALL, THAR-VW3, and TB-VW.  Seems to work fine after install. Customer says after sitting he can only operate the OEM fob when standing next to vehicle. Will work about 50 feet away on the first press of lock button but after that it needs to be within 10 feet. I have replaced batteries in remotes. Would this install affect this? The only other thing I can think of is that I didn’t connect MUX door lock or trunk wires from EVO but assumed those are used only when an RF KIT or remote starter is added. I have tried with option A5 off and on with no difference. Service # 001A06 904444 Thanks, mike

"would standalone setup cause OEM fob to lose range or not work:

-No. We do not change the way the OEM fob works in anyway, we merely monitor the signals for lock and unlock.
