eBay Escalade Keyfob issue

[ccole]

I’ve been running a pair of these knockoff Escalade fobs in my 07 LTZ for a couple years. In the last couple months 2 problems have popped up. I don’t believe there related but both involve the fobs.
#1 Recently the primary fob no longer opens the lift gate. Both bottom buttons(lift& glass) only open the glass. The secondary remote works as intended. Any advice?

#2 Both remotes no longer remote start the vehicle. When the button combination is pressed the light flash appropriately and the fuel pump primes but no starty start.

Anyone dealt with this or have TS recommendations.

Thanks

Open them up and clean the contacts, also replace the batteries.

My thoughts exactly.

Any CELs? These truck won’t auto start with any codes set.

100%. The remote start was CEL related from removing the 4/8 cyl module. I'm going to re-enroll the primary fob then go from there.
Thanks everyone for the feedback!
