I have a 2007 RDX. I see lots of options for cheap key fobs for my vehicle. I picked up a $35 dollar one online and I was able to program it. I did get the key cut on it, but found the key sticks in the ignition and is very hard to pull back out. Also I can't actually turn the ignition switch to the on position. I ended up using the electronics portion of the new fob and connected it to the old Acura fob key section to get a usable remote. Is this normal for the new keys to stick? I currently have 3 working keys for the car, plus a 4th broken one. How many fobs can you actually program into the vehicle, before you have to wipe its memory and start fresh when doing yet another fob? Im debating to get another aftermarket fob, to replace the flaky buttons on one of my partly working fobs. One of my keys is also a buttonless key, but it able to start the engine with. Any thoughts?
