How do I release the circuit board from the smart key after the battery carrier has been removed? I cannot find a video or good description for releasing the board.
Look at the top picture in my previous post. There is a white retainer that holds the circuit board in place. Remove the white retainer with a small pick and the circuit board will slide out.
Possibility of replacing factory system with aftermarket?
I thought getting information on my Lexus was a PITA! It seams I had no idea what it would take to obtain info on my "new to me" Mercedes S600. However I love this machine so much I'm committed to finding out as much as I can.
My car only came with the single key which does everything including the keyless go feature. However since it is my only key I am VERY nervous about it breaking.
I have read a metric butt ton of information about all of the pitfalls of getting replacement keys and I have resigned myself to the fact that I will most likely have to shell out a few hundred dollars from the stealer to get said replacement key. And if I also want that key to do the keyless go I have been told to double the cost.
However, I was thinking, how difficult would it be to completely bypass the factory system and install a high end aftermarket security system? I know from recent experience that the high end Viper or other similar systems go for around $300 to $500 and they do everything the factory system does in addition to remote start which amazingly my space shuttle of a car can't do. Any thoughts? Thanks,
Based on posts in this thread I decided to replace my smart key 'case'. I purchased a replacement from seller - yourkeylessremote on eBay for $25.70 delivered.
It arrived today and is nearly identical to the factory key case. The only difference I could see was that the plastic had a little more texture to it's surface. The original is smooth. Swapping out the electronics took about 5-10min thanks to the instructions provided by others and it worked perfectly when opening/closing the doors and starting the engine.
My dealer could not guarantee to get me a chrome key. They would order one but they said I might end up with a regular one which I would then own since the key had been cut. It also appears that there is a slight difference in the shape of the cut key compared with the original 4 button smart key.
I purchased a used old style key on eBay to replace a cracked key. I found it is very easy to pull the old circuit board out of the old key and slide it into the new key.

With my new surgical confidence, I then removed the board from the old working key and rebuilt the new key with the old board and white plastic keeper bar.

Hey guys, I know this is an old post but I am finding myself in this dilemma right now with an older Smart key.
I'm very familiar with how to change the battery, but changing the circuit board is where I'm having trouble with. I know many of you have had success in changing it, but I cannot seem to find the "white retainer clip" that is mentioned. Here is a photo of my key. I am a bit stuck as to how to remove the circuit board. What tool can I use that will unlock the retaining clip, and what exactly am I looking for?
Any help is greatly appreciated, as I am very stumped right now.

Your pictures show the white plastic retainer in the middle. Carefully remove it and the circuit board will pull out.

Thanks for your response. But a part of my question was "how do I remove the plastic retaining clip? What do I stick in there to grab it? And which piece of it do I grab?"
I am having an uber blond moment right now...

I used a hook made from a paper clip bent into a "J" shape. I caught the retaining clip in the middle and pulled until it popped out.
