In the key business for 28 years and we are dealing with a 98 ML320 with all 8 slots utilized. The owner has taken it to almost
every garage in the city (greater Milwaukee) and has exhausted herself emotionally, and financially. The dealer wants more for the repair than the truck is worth. The vin is 4JGAB54E7WA013361, a W163. We may be able to locate a wrecked similar vehicle with keys.
Is it possible to switch the AAM, ECU, black box under the dash, steering column antenna module, etc. to allow this vehicle to run
without spending $5,000? We have the capability of transferring the chip(s) from the crash truck to laser cut shell keys so that the physical locks can remain. Can anyone tell us if this is possible, what components do we need to switch from the crash truck and if you know a source on these parts. Please don't speculate, only respond if you are sure of yourself. Any help is much appreciated. Assuming we can get the truck running we are going to recommend she dispose of it. She has tried swapping out ECU and AAM through local salvage yards, and they have her old modules on exchange and they are not available. There is a company in Pennsylvania that sells an overwriting tool that plugs into the OBD2 port and supplies 2 transponder keys and I have rented this device once in the past to successfully make those keys run this truck. They don't rent it anymore, you must buy it, and it's expensive. I'm reluctant to invest because of the module switching she's done. For the same reason I don't think that ordering a key through Mercedes and putting "duplicate 1" in the comment line on the key order (or any number other than "1" after the word "duplicate") will be successful. Hence this path seems fruitless due to module swapping.

This is an immediate need. Thanks for your prompt attention if you can help in any way.

    Actually there are even more computer modules to deal with, such as the Instrument Cluster and the CCM or Command Control Module. So the list isn't really complete. However other than the components with the embedded chips, why not just do complete reprogram of the large computers. I have replaced a Command Control Module, an ECU and an Instrument Cluster Computer in these vehicles and the Dealership reprograms these computers, part of which are the security codes.
    Have you contacted Mercedes directly with this problem? Not all Dealerships are the same in terms of their grasp of the technology, I would contact the Factory District Service Engineers. I used to be a Lead Tech at a very large Volvo Dealership and the District Service Engineer had information that we at the Dealership could not even imagine. They also have direct contact with the engineering team who designed the system in question. Most of the high quality European Vehicles have the same Bosch based systems, including the lazer cut keys etc. I would contact the District Service Engineer. Sometimes the Service that you receive at a Dealership is only as good as the skill of the Technician and the need of the Service Writer to generate a commission for themselves, I have seen, firsthand, Service Writers recommend a solution that paid them more than a much simpler solution that was less profitable. I hope that my suggestions give you some food for thought.
