I did this to both the driver and passenger front and now my key fob works again. There are YouTube videos on how to do this, it's very easy.
Thanks for your reply. Yeah, unfortunately I'll have to take apart my door panels again and return the actuators and replace the motor inside the OEM actuator as well.
I cannot stand having the alarm/anti-theft issue, it's very annoying. I had to unplug the the alarm horn to stop it from going off, haha.

Thanks again, mate.

I just did mine yesterday and now I'm having an issue with alarm going off occasionally. If it continues to do this I'm going to end taking the 2 rear aftermarket door actuators out and replacing the the motors on them. Hopefully that fixes them. Don't want to dish out $600 for something as simple as door actuators. Good luck!

Hate to break it to you guys but that listing is for Chinese Knock-Offs.
Pretty tricky, they printed out OEM stickers to put in their pictures but I have seen enough actuators to tell the difference.

Here is a tutorial to explain some of the problems you guys are experiencing.

Your best bet is to buy some motors and rebuild your original OEM actuator. Way too many fakes going around these days.
