thank you for the referrals, glad i could help

 

Unfortunately, I throw away old case without knowing that the chip was still there. Newbie mistake! Anyway, I just ordered the new key at NeedsWings. Thanks guys for the advice.

 

You are absolutely correct. If you know your SKREEM is bad and you can get one in a decent amount of time from a local dealer or supplier like Needs Wings, that is what we would recommend. No programming is needed. SOS services include diagnostics and verification of repair. Also, keys and modules on these cars and the older Mercedes are becoming hard to come by, so we can often repair the original modules or supply a replacement. The above posted prices are incorrect. Please get pricing direct for sosdiagnostics. SOS Diagnostics has been able to help many Crossfire owners of whom the dealer told them they needed a new SKREEM and then they got it and had the same start-die issue. We have the same issue with Dodge Sprinters. So having all the modules present for testing means SOS can confirm the fault before ordering parts (if they are even needed). I know this is an older post, but it keeps coming up with Crossfire owners, so I wanted to address it.

 

i recognize this is an old msg on topic, but my crossfire is sitting in shop now for 1 1/2 months trying to sort out if i need a new skreem or new fob or both, & if i get 1 and no positive results, what wd be next ?! Etc. ...BUT, your "accidental" comment of the chip in the fob slipping seems so simple! Afterall, i only dropped key 3 feet, so so how could Skreem just happen to need replacing after that drop? So, off to the shop to pick up key, dismantle & see if chip moved out of place in fob.
So help, how big is chip in fob; what does it look like? Can i assume it is in front of battery in fob ?

 

Click on Index of Crossfire problems and repairs .... in my signature and scroll down to Fob repairs, then click on the first article. It has photos in it that show the chip. Good luck.

 

It's worth checking it out, I guess. I've been wondering if a sudden shock (like dropping fob) can damage the chip.
Check out the great data in onehundred80's signature.

I have an extra OEM fob if anyone interested.

 

Unless someone has taken the remote apart in the past and left pieces out, there is no way for the chip to move, even if dropped. You likely have another issue. If your guy cannot solve it, have him remove the parts and send them to us for testing. Most locksmith shops also have tools that can test the key and make sure the transponder is not damaged. If a key reading tool cannot read the transponder, it may be damaged. However, the transponder chip is very durable with a low failure rate due to impact. Usually only physical damage / crushing will kill them.

 

Does the FOB tester test the chip or just the transmitter that locks/unlocks (and related) the car. I have seen the ones in advance auto and also seen one from a dealer (for a Camaro) that just test if the FOB transmitter is working (battery integrity of the FOB). Did not know the locksmiths one could test a transponder chip. What would that tester get back besides the transmitter working to lock/unlock (or related), a number(?), a code(?), has to be something that could be interpreted into a code for the related electronics (like the SKREEM). Please tell me the name of, and part number (I would like to read up on it).

There are testers for transmitters and testers for transponders.
