(Many inexpensive aftermarket secrets only work when placed into the slot).Frequently Asked Questions (FAQ)1. Can I buy an utilized Mercedes key on eBay and program it myself?
No. When a Mercedes key is programmed to an automobile, it is "locked" to that VIN. It can not be reprogrammed to another car using standard tools. Moreover, Mercedes keys require specific software and hardware to program; there is no manual onboard series to do it yourself.
2. The length of time does the programs procedure take?
If the locksmith professional has a working key to copy, the procedure normally takes 30 to 60 minutes. If all keys are lost, it might take 1 to 2 hours, as the information extraction process is more complicated.
3. Does the car need to be present for key shows?
In many cases, yes. The programs tool needs to interact with the automobile's EIS module to integrate the new key. Nevertheless, some advanced locksmiths allow owners to mail in their EIS module and a working key to create a duplicate.

Keyless-Go enables the motorist to approach the car, unlock, and start the engine with a button without ever getting rid of the key from their pocket. These keys consist of advanced distance sensors and radio frequency transmitters, making the hardware and the programming more pricey than standard "SmartKeys."
