Try resend the cloned one to the shop. Ask them to "retune" it one more time.
I dont know how to explain this, but sometimes, the remote would be "out of tune" by itself. Depending on the tuning equipment used, IC board of the remote, the quality of remote (the cheapo ones are terrible, and not worth the time using it).
my remote also out of tune..replaced with new battery still didnt work well...
untill i dismantle the remote and left bare remote chip/board....and when it didnt work i will randomly touch the ic/resistor and even remove-reinsert battery to get it working again...
