So, I brought in my car for its first maintenance last week, and I complied about the truck lock not being able to lock properly with my metal key. So, the dealership said they ordered a "tumbler" and that it came in yesterday. I took it to the dealer today, and they "worked" on it for 6 hours and finally according to my service advisor, the shop foreman came and asked the tech what he was doing, and that the 05's don't have valet truck locking capabilities. I even called 1800formerc, and they confirmed it for me as well.

What the hell is the point of having a "valet key" that only works for the glovebox? I don't get it. Why did MB get rid of this? Damn, this sucks.

 

Read your manual! Just don't assume you have something. LOL

 

Please... don't give me that b.s. this has been standard on every MB since god knows when. Even companies like Toyota have it in their cars. What's the point of the manual lock on the trunk then? It's useless. Why put a lock there if it doesn't do anything.
This isn't my first Benz, and this is a no-brainer that anyone would expect. I read the manual, and didn't think MB would be dumb enough not to include this...

 

The key is to open the door lock on the drivers door or to lock the glove box! My 2003 Coupe does not even have a tumbler in the hatch! Only the handle and no way to manually lock the hatch! Also not sure what the purpose would really be for a trunk lock since it unlocks with the power locks anyhow and then all you have to do is pull the handle! I have a Coupe, but isn't there an internal trunk release in the car anyhow? Also don't you have a trunk pop button on you smart key? Excuse my ignorance but when I got mine I only got two smart keys and nothing else, not even a wallet type key for the drivers door!

Edit: Point of the manual lock is obvious, it is to unlock the trunk in an emergency where either your smart key does not work properly or you have no power in the car!

 

actually...when i lock my trunk with the valet key..it cannot be opened by the remote, by unlocking the doors, or by pushing the open trunk button. it can only be opened after i unlock it with the valet key...

 

I also tried the valet lock and the trunk won't pop when I use the remote trunk pop on my smartkey

 

true, the coupe doesnt have the key in the trunklike the sedan. though the sedan works as a valet, when you lock it it is supposed to not open.

plus MB's have had valet restrictions on the trunks for as long as i can remember. freaking nicedeboy needs to shut the F**K up and think before he speaks.

 

Not gonna happen. Remember, he is a self claimed brain damaged boy driving a $26k C55. He is a troll. Kerplonk to him

 

Just curious, if you had a split rear fold-down seat, wouldn't it make locking the trunk with a valet key pointless since you could still get into the trunk through the fold down? Or does the valet key lock the fold down seats as well?

 

I had split fold down seats in my w202, and if the w203 split fold downs are anything like it, then the handles are in the trunk and you still couldn't get into the trunk if it was locked with the valet key.

 

The rear seats lock in Audi's and the split seat is STANDARD. Cheapo MB engineers

 

The Sales Manager showed me I had the valet key and explained it's use. He told me that you put your stuff in the trunk, lock it with the key, take the key and give the beeper to the valet and he wont be able to open the trunk with the beeper. I haven't checked if it works though.

 

That's exactly what they explained to my wife on her C320 SS. And it works !! The SmartKey trunk release button will not pop the trunk after you've locked it with the valet key.

Speaking of which, on C320 Coupe, I was able to get a SmartKey with trunk release button (long "Citronic" salt-water story ). Anyway, it works great ! Additionally, I set the SmartKey to unlock Driver's side door first with one press of the button, and unlock Pass side and trunk with second press of the button. Too bad the coupe doesn't have the valet lock on the trunk though. Additionally, my daughter can get it in to the trunk from inside the car by taking down the split rear seats, and then popping the GREEN release button inside the trunk. She thinks that's the craziest adventure since Mr. Toad's Wild Ride !

 

good thing Mr. Toad is Green.

i still need to do my second smart key. i thought 'd give it a couple months though!

 

ROFL! That's cute.

 

me too !!! i did find some really old TSB that said that those little digits on the side of the SmartKey (probably worn down from use) had to be replaced for the SmartKeys that "happen" to have the Trunk Release Button on them (with a different set of little digits). I gotta find those numbers, I wrote them down somewhere. Anyway, that convinced my SA to swap out the keys, without much ado about WHY the key was not working.
Gotta LOVE gullible SA's !

and gotta LOVE the perks of driving a COUPE !!

 

i love my coupe! wouldnt have it any other way. just getting mine exactly the way i want with my last few mods!

 

I still have a lot more to do !! It never ends... but looking at the Sport Sedan parked next to my Sport Coupe, it sure seems that there's so much more you can do to a Coupe to make it really different, sticking with OEM MB and AMG parts only.

 

yeah i m not going as far as AMG mods. well i have the brakes and sways, and maybe a front bumper and rear apron eventually. right now im sticking with convienence OEM mods. CLK mods to really stand out!

 

So if the MY05's don't have the valet truck lock option, why do they still have a tumbler there? Does the metal key still lock and unlock the trunk? And if you do lock it with the metal key, are you saying that you can open it by using the remote?

 

That was my question, I have no idea why there's a tumbler there... You CANNOT lock it with the metal key. The key ONLY turns 45 degrees, and then you can't pull it out or anything. I guess the tumbler and metal key are only for times where you have no battery, b/c just getting to the key area is a pain unless the trunk is up.

God, I have no clue what MB was thinking when they did this...

 

No, reread what PRHelo said (he has an '05)...the valet key, locks the trunk, and keeps the trunk from being open by the remote. Just make sure you give the remote to valet and you hold on to the metal key. If you listen to the trunk when use the remote, you can hear the stages of disengage, I remember hearing it the 1st time thinking it was crazy....but obviously there some engineering that only releases the trunk if it is not engage by the lock tumbler.

 

hmmmm....i just tried to do it on my '05 and you cannot lock the trunk! all u can do is turn the key 45 degrees and u cannot pull the key out after u do that

hope no valets jack my stuff

 

Just read the manual, I know it's hard, but do it , you'll be amazed at all the stuff you'll learn.

 

Actually he said, what the Sales Manager told him....
Jan Ken Po: I tried it on a 2004.5 and it works. Valet key locks the trunk, and then when you try to push the button on the SmartKey to open the trunk, nothing happens.

PRHeloPilot: can you check your 2005, and lock the trunk with the valet key, then try to open the trunk with your SmartKey to see if it opens.

Hopefully, this will settle this debate !
