Recommended aftermarket keyless entry systems

[SulkierLizard]

After finding out my 2000 Grand Prix SE didn't come installed with remote entry thanks to richtazz I have been looking for some aftermarket keyless entry systems to install on it. So I was just wanting to to know if any of you guys have installed these and what your opinions are on them? I have a feeling some of them out there are cheap and of poor quality. Here are a few I have found on Amazon.

I've never been a fan of bulldog. I installed a bulldog remote start/keyless entry for a guy in the shop. He provieded the new unopened package (just like the link you sent me) and it was missing a hood pin saftey shut down switch and one of the relays were bad right out of the box. I had to forgo the safety switch for the time being, and he went without parking lights flashing when it remote starts in order to use that relay for the ignition system.

Not sure on the other link, I've never use it.

While you are at it, why not install a remote starter with keyless entry?

The brand which I've installed a few times and like quite well due to its quality is ultra.

And here is a link to just an ultra keyless entry, no remote starter.

I have also heard good things about scytek, though never used them.
