ML (163 Chassis) Key Re-Chip Service

More and more Mercedes ML model vehicles are showing up with bad keys, AAM's, and ME control modules. Data is scrambled, the immobilizer LED on the dash will not flash, and the vehicle no longer starts. Fault code P1570 is also usually present in the ME. Further complicating the situation is the design of the immobilizer system which limits the vehicle to 8 keys. Once all 8 have been issued by the dealer no more replacement keys can be obtained. The current dealer option requires replacing the ME, AAM, buying new lock sets, and paying for installation and programming.

We have developed a process to repair all affected components and restore the vehicle to normal operation. By sending us the ME, AAM, and keys, we can reprogram the modules and re-chip the keys to get you or your customer on the road again.

The following items will be required for this service:
  • ME (Engine Control Module)
  • AAM (All Activity Module)
  • Keys (Up to 7 remote keys and 1 valet key)
  • Proof of ownership (copy of registration, title, etc.)

Currently priced at $1,500.00.

What caused this to happen?
The common failure for the Key/AAM's is low voltage situations usually while starting the engine. This can be caused by:
  • A poor vehicle battery
  • Weak ground connections at the battery, engine, or chassis
  • Bad contacts in the ignition key electrical assembly
  • Occasionally a poor fuse box connection
If these potential issues are not corrected before the re-chip service it is likely that the damage will reoccur!

I'm out of keys or only have 1 left!
You can actually use keys from another vehicle as long as the year, model, and FCC ID on the remote match. The FCC ID can be found stamped on the back or side of the remote. Please be aware that you will need to buy new metal blades for the used remotes that you buy. New blades can be purchased at the dealer and there should be no limit on them.
