One working key can feel like enough, until it is lost, damaged, or locked inside your vehicle. If you drive a Mazda or Subaru in Indianapolis or Central Indiana, making a spare before you need it can help you avoid the added stress and potentially greater expense of an All Keys Lost situation.
KEY BOSS LOCKSMITH, a.k.a KEY BOSS SECURITY AND DOOR SOLUTIONS, provides local automotive locksmith service for supported Mazda and Subaru vehicles. We handle spare keys, key fob replacement, key cutting, programming, and vehicle lockouts. We’re a certified and insured, BBB Accredited Indianapolis locksmith, not an out-of-state dispatcher or call center.
Mazda and Subaru key replacement for supported vehicles
Your replacement key depends on the vehicle’s year, model, trim, and security system. Some vehicles use a transponder key with a traditional ignition. Others use a proximity smart key and push-to-start ignition. The key and programming process can differ even between models from the same manufacturer.
We assess requests for supported Mazda models such as the CX-5, CX-30, CX-50, CX-90, Mazda3, Mazda6, and MX-5 Miata, along with Subaru models such as the Outback, Forester, Crosstrek, Ascent, Legacy, and WRX.
That includes inquiries about 2026 Mazda and Subaru keys, but we confirm the exact vehicle before promising a service. Late-model security systems change, and not every year, trim, or configuration can be programmed roadside. Some jobs may need to be completed in-shop.
Our automotive locksmith service in Indianapolis can help you ask about:
- Spare or duplicate car keys
- Transponder keys and key cutting
- Smart or proximity key programming
- Push-to-start fob replacement
- Key fob programming
- All Keys Lost service
- Broken-key extraction and vehicle unlocking

Add-a-key or All Keys Lost? Tell us which applies
You still have a working key
If you have one working Mazda or Subaru key, ask about adding a spare. We’ll verify the key type and vehicle system, then explain the available approach and pricing before work begins. A spare made now may help you avoid a more complicated situation if the last working key is lost later.
That’s the idea behind our “One Key Is No Key” philosophy: don’t wait for an emergency to consider a backup.
You have no working keys
If all keys are missing or unusable, tell us clearly that this is an All Keys Lost request. It is not the same as duplicating a working key. The procedure may require additional security steps, key generation, cutting, and programming. Depending on the vehicle, the job may take longer or cost more than adding a spare.
We’ll collect the details needed to assess your vehicle and confirm whether mobile or in-shop service is appropriate. When required, have your VIN and proof of vehicle ownership available.

Key fob problems, broken keys, and lockouts
A fob that won’t unlock the doors does not always mean the same problem as a vehicle that won’t recognize its key or start. The symptoms help us determine what information to gather and whether you may need a replacement fob, programming, a key cut, or a different diagnosis.
If your key has broken, don’t force the remaining piece or try to pry it out. We can assess broken-key extraction and related key or ignition concerns for supported vehicles.
Locked out? We prioritize non-destructive vehicle entry whenever the vehicle and circumstances allow. We assess the lock and choose a suitable professional method to help avoid unnecessary damage to the door, window, trim, weather stripping, or lock.
We understand that “no drilling” matters to customers. We do not drill simply for convenience, but no locksmith can promise drilling will never be necessary. If a damaged mechanism or vehicle design prevents safe non-destructive entry, we explain the options before proceeding.

We provide mobile service across Indianapolis and surrounding Central Indiana communities, including Carmel, Fishers, Westfield, Noblesville, Downtown Indianapolis, and Greenwood. Availability and arrival time depend on your location, traffic, current calls, and the service required. Call to check scheduling rather than relying on a fixed arrival-time promise.
