I purchased our 2012 Mercedes E250 AMG Estate a few years ago and recently utilised the spare key provided with it for the first time.
The manual key shaft can only be inserted halfway into the lock barrel, despite the cuts seeming identical visually.
The buttons on the fob remain nonfunctional despite replacing the battery.
What methods may I employ to verify the accuracy of the provided spare key? The key shaft is evidently incorrect, since it fails to engage with the lock (the standard key operates effectively both electronically and manually); however, I would like to ensure that the spare key functions electronically. Is there a specific programming sequence to follow? I lack any communication with the seller (private).
I appreciate your assistance in advance.
The replacement key is nonfunctional. E250

Are you certain that the shafts of both keys are identical? I cannot provide a definitive solution to your issue; however, it appears that the prior owner may have misplaced the second key and subsequently purchased a comparable key online.
I recommend visiting your local main dealer with your V5 registration document and proof of identity to enquire if they can conduct a test for you.

If simultaneously pressing the lock and unlock buttons until the red light flashes proves ineffective, there are few options available. The distinct cut of the blade is an obvious indicator, to be frank. A new key for a 2012 model may currently be acquired for £90.
Thank you for both responses.
Initially, I attempted to push the buttons on both my standard key and the new one, but there is no red flashing indicator, despite my regular key functioning properly.
The new key shaft closely resembles the original; it may require lubrication, as it is evidently fresh.
I received numerous invoices for parts purchased for the vehicle, including one dated 01.10.2022 for a 'Mercedes 3-button' for a net price of £95. I have contacted the supplier, who is supposed to return my call, but I have yet to receive a response.
Since it is evidently a fresh key, I assume it has not been programmed. Is it a dealer task, or should I adhere to the different directions available on Google regarding inserting the key into the ignition and hitting multiple buttons repeatedly? I am unwilling to proceed if it may disrupt the functionality of my primary key and the vehicle.
Could someone provide a precise technique, please?
Thank you very much.

Certain keys can be programmed by specialised locksmiths using the requisite software, while others are sent pre-coded from Mercedes Germany.
£95 appears exceedingly inexpensive, especially for a key provided by a specialist; most typically cost over £150, and occasionally more. The cost from Mercedes ranges from £250 to £300, and the blade was previously ordered and paid for as a separate item.
