Automotive locksmith in Indianapolis — transponder keys, proximity fobs, lost-all-keys

Mobile key cutting and programming for transponder keys, proximity fobs (push-button start), and high-security European keys. Most makes 2010+ done on-site in 45 minutes.

Automotive locksmith in Indianapolis — transponder keys, proximity fobs, lost-all-keys

Losing the only key to a modern vehicle — or locking a transponder key inside — is not a $50 problem anymore; dealer key replacement for a 2020+ vehicle with a proximity fob can run $400-$800 and require a 3-day wait, while a mobile locksmith with the right programming equipment resolves it in 45 minutes on-site for 30-50% less.

For standard transponder keys (most domestic, Japanese, and Korean makes 2010-2019), we cut a key blank matched to the bitting code from your VIN and program the chip via OBD-II port. Total time on-site: 30-45 minutes. Cost: $150-$300 depending on make.

For proximity fobs on push-button start vehicles (most makes 2012+), we use manufacturer-specific diagnostic programmers (AutoProPAD, Autel IM608, T-Code Pro) to add a new fob to the security module. Total time: 45-60 minutes. Cost: $250-$500. Lost-all-keys scenarios on Toyota / Honda push-button vehicles require an additional security module reset — Anna captures this at intake.

Automotive Locksmith — Keys, Transponders, Fobs — common questions

Can you replace a key for any car?
Most makes 2005 and newer — yes, on-site. European luxury (BMW, Mercedes, Audi, VW) 2008+ requires additional equipment and extended programming sequences; we handle them but with a price premium. Anna confirms make/model at the booking call so we arrive with the right blank and programmer.
How much does a new car key cost?
Standard transponder (2010-2019 most makes): $150-$300. Proximity fob (push-button start 2012+): $250-$500. High-security European: $350-$700. Lost-all-keys scenarios add 30-60 minutes and $50-$150 in additional programming. All quoted on the phone before dispatch.
Will the locksmith key work as well as the dealer key?
Yes — identical functionality. Mobile locksmiths use the same OEM key blanks and programming protocols as dealer service. The difference is on-site speed and 30-50% lower cost. Some makes (Tesla, Rivian, some Lucid trims) still require dealer service; Anna confirms at intake.
What if I lost ALL my car keys (no working spare)?
On most makes, no problem — we use the VIN to generate the key cut and program the new key from scratch. Toyota, Lexus, Honda, and Acura push-button vehicles 2018+ require a security module reset, which adds 30-45 minutes and a small fee. We handle the scenario in one visit.
