Navigating the complexities of Mercedes Sprinter Key Fobs can be frustrating, especially when you’re looking for cost-effective solutions. A common question among Sprinter owners is whether aftermarket key fobs, like the S15TK1 key blank, can be programmed to work with their van’s ignition system. Let’s delve into what you need to know about Mercedes Sprinter key fob programming and aftermarket options.
Aftermarket Key Fobs: Cloning vs. Programming
The original poster raises a crucial point: are aftermarket key fobs truly compatible with Mercedes Sprinters, or do they require special handling? It’s suggested that some aftermarket keys might not be identical to genuine Mercedes-Benz key blanks and could necessitate a cloning machine for duplication. This contrasts with the possibility of programming a new key directly to your Sprinter if you already possess two functioning keys.
DIY Key Programming with Existing Keys
For those fortunate enough to have two existing, properly programmed keys (not clones), there’s a potential DIY route. The original post mentions ordering a pre-cut key from a source like Berry Dodge for around $48 and programming it yourself. This method hinges on the Sprinter’s system allowing the programming of a third key (up to a maximum of eight) when two valid keys are present. However, this isn’t helpful for owners who only have a single working key.
The Challenge of Key Cloning and Dealer Programming
The lack of locksmiths with key cloning equipment in certain areas, as mentioned in the original post, highlights a significant hurdle. If cloning isn’t an option, the alternative often leads to dealership programming, which is often described as a cumbersome process. The provided PDF link (http://66.132.131.97/btc/barloworld/sprinter/maintenance/Key_Programming.pdf) hints at the complexities involved in dealer key programming.
One-Time Programmable Chips and Key Fob Numbering
There’s a question raised about whether the key chip programming is a one-time event. This is a critical detail as it would impact the feasibility of reprogramming used keys. Furthermore, the post points out that Mercedes-Benz key fobs have sequential numbering. New vehicles come with keys marked “1” and “2,” and replacements must follow this sequence. This numbering system implies that simply buying a used remote online and expecting a dealer to program it might not be straightforward due to these pre-programmed designations.
In conclusion, while the idea of using aftermarket Mercedes Sprinter key fobs or DIY programming is appealing, it’s clear that the process can be complex and dependent on factors like having existing keys, the type of aftermarket fob, and the availability of cloning services. Dealer programming remains a reliable but potentially inconvenient option. Further research and consultation with locksmiths or Mercedes-Benz specialists are advisable when dealing with Sprinter key fob issues.
