The evolution of car security has been remarkable. We’ve moved from simple mechanical keys to complex keyless entry systems. High-end car manufacturers have invested heavily to protect against theft, but how secure are these systems, really? And what about the used key fobs market? As an auto repair expert and content creator for keyfobprog.com, I’ve delved into the world of key fob security, and what I’ve found might surprise you, especially if you’re considering buying or selling used key fobs.
Recently, I had the opportunity to visit a leading private forensic laboratory in Europe in Mayen, Germany. Speaking with Manfred Goth, a certified police forensic expert, opened my eyes to the hidden world of vehicle security and the data embedded in our seemingly innocuous key fobs. Goth’s lab works with major European insurance companies, uncovering fraud in cases of theft, arson, and burglary. Their expertise even extends to consulting with police on covert entry and security system bypass, partnering with the Lockmasters Group, specialists in covert entry tools and locking system vulnerabilities.
While my work typically focuses on physical lock security, the visit shifted my perspective to car key fobs and their associated vulnerabilities. Like many, I use keyless entry but hadn’t deeply considered the security or privacy implications. The idea that my key fob could store vehicle data, potentially accessible to insurers or law enforcement, was a revelation. This became starkly clear during my time at Goth’s lab and Lockmaster’s office.
Goth was investigating a BMW theft case, a brand known for storing extensive data on its keys. He demonstrated a decoder from Abrites, a Bulgarian company specializing in vehicle electronic decoding and bypass systems. Abrites develops tools for locksmiths and restricted versions for government agencies, capable of hacking immobilizers, keys, locks, and car computers. These tools can be used to enter vehicles, plant devices, clone or decode keys, extract data, or even steal the car. Alarmingly, these tools aren’t just in the hands of authorities and locksmiths; car thieves are using them too.

Plugging a BMW key fob into the Abrites decoder, Manfred extracted data within seconds: the Vehicle Identification Number (VIN), mileage, fuel level, and last driving time. Newer keys even store GPS data. This data retrieval has significant implications, especially when considering the market for used key fobs.
Consider insurance fraud. Many “stolen car” claims are, in fact, false. In Europe, insurers often request keys for examination during claims. Unbeknownst to many, the data on these keys can be used against them in fraud investigations or claim denials. Imagine a scenario: a driver reports their car stolen three days prior and hands over the keys to prove they weren’t left in the vehicle. However, the key’s memory reveals the car was driven the previous day, exposing a fraudulent claim. This data vulnerability extends to used key fobs as well. If a used key fob retains such data, what are the privacy and security implications for both buyers and sellers?
Furthering my investigation, I visited Lockmaster headquarters in Bergheim to witness key decoding and car theft techniques firsthand. In an interview with Enrico Wendt, Lockmaster’s Operations Manager, I saw a BMW key fob decoded. In a follow-up, Sascha Wendt, Technical Manager, demonstrated how easily a new Audi could be stolen. This ease of access raises serious questions about the security of keyless entry systems and, by extension, the potential risks associated with used key fobs. Could a used key fob be easily reprogrammed for malicious purposes, or retain data from its previous vehicle?

While data storage on keys is ostensibly for vehicle maintenance, law enforcement and insurers influence automakers to store more data, mirroring the trend with smartphones. This increasing data collection raises privacy concerns, especially when used key fobs enter the market. Are these fobs properly wiped? Can they be traced back to previous owners or vehicles?
Vehicle keys are just one aspect of ongoing security battles against covert entry specialists, law enforcement, criminals, and hackers. I learned about high-tech car theft devices, also from Bulgaria, capable of stealing expensive cars. Furthermore, I was briefed on how a key fob for a top German luxury vehicle could be replicated via its infrared port and a laptop, thanks to Polish hackers. Car manufacturers are responding to wireless entry system flaws, with innovative solutions emerging, like one from a Swiss inventor I interviewed in Zurich. The security landscape is constantly evolving, and the used key fob market adds another layer of complexity.
So, what does this mean for buying or selling used key fobs?
- Data Security Risks: Used key fobs might retain data from previous vehicles, posing privacy risks for both buyers and sellers. Ensure any used key fob you consider purchasing is properly wiped and reprogrammed by a professional.
- Reprogramming Complexity: Reprogramming used key fobs isn’t always straightforward and may require specialized tools and expertise. If you’re selling a used key fob, be transparent about its reprogrammability. If buying, verify it can be correctly programmed for your vehicle.
- Potential for Malicious Repurposing: In the wrong hands, a used key fob could potentially be reprogrammed for nefarious purposes. Source used key fobs from reputable vendors.
- Security Vulnerabilities: Used key fobs, like new ones, are susceptible to hacking and cloning if not handled and reprogrammed securely.
For those looking to Sell Used Key Fobs:
- Consider data wiping services: Explore services that can securely wipe data from key fobs before resale.
- Be transparent about history: If possible, provide information about the key fob’s origin and vehicle it was previously paired with (without compromising personal data).
- Partner with reputable buyers: Sell to businesses specializing in used key fob recycling or reprogramming, ensuring responsible handling.
For those looking to buy used key fobs:
- Verify reprogrammability: Confirm with a locksmith or dealership that the used key fob can be programmed to your specific vehicle.
- Inquire about data wiping: Ask if the used key fob has been professionally data-wiped.
- Use reputable sources: Purchase from established vendors or locksmiths specializing in used key fobs to minimize security risks.
The market for used key fobs presents both opportunities and challenges. While repurposing these devices can be cost-effective and environmentally friendly, understanding the associated security risks is paramount. As technology advances, staying informed about key fob security is crucial for both consumers and professionals in the automotive industry.
