Is it typical to get a replacement key?

[tr4s]

The AA is now replacing a lost key and estimates that the process will take several hours due to the need of removing the dashboard. Is this considered typical, and if so, what is the reason for it?
Thank you.

This seems really peculiar to me.

A Mercedes-Benz dealer may provide a new key that is specifically programmed for the automobile, without the need to disassemble the vehicle.

I will contact them to ascertain the reason for their need to do such action.

Presumably, this is due to their lack of access to the central computer of MB and their inability to program a new key for the automobile via the approved method.

Is their intention to change the Electronic Ignition System (EIS) located beneath the key slot, rendering any additional keys for the automobile inoperable? This does not sound accurate to me.

I have had my keys duplicated in under 40 minutes, without the need to remove the dash. It is likely that they are also changing the electronic ignition switch (EIS) simultaneously. Will the doors still be able to lock and open with the provided key?

[tr4s]

I spoke with them and they informed me that they need access to the Enterprise Information System (EIS) in order to get codes. Uncertain about the accuracy of this statement.

Yes, that is somewhat right, and he will essentially delete your Key EIS, not the dashboard. It seems unlikely that it will take that amount of time. He will allow some flexibility in case any unusual occurrences are encountered. I have recently had a thought. If he intends to replace your current electronic steering lock (ESL) module, it would indeed need a few hours, involving the disassembly of a portion of the dashboard. What is the reason for wanting this to be accomplished? If the task is being completed, then it is satisfactory. If the Electronic Steering Lock (ESL) malfunctions, the vehicle will not start until the module is replaced with a genuine Mercedes one or a simulator, which is a more convenient solution in the long term. It seems that he intends to extract your EIS key module and read its contents in order to create a new key. The system will display the number of keys now programmed and provide the opportunity to add more keys without requiring the deletion of any existing keys, if desired. If the reader is on the bench, then the EIS is withdrawn. It is not a significant matter.

If the automobile is manufactured after 2015 or 2016, it is unlikely that the laptop locksmiths will have the necessary software available. Mercedes has not yet made it available for sale, as far as I know. Therefore, it is conceivable that the AA is adopting this strategy.
