The Truth About Aftermarket vs. OEM Car Keys in Phoenix, AZ

If you’ve ever lost a car key or needed a spare, you’ve probably faced a choice: OEM or aftermarket? Dealerships usually push OEM keys (Original Equipment Manufacturer), while mobile locksmiths often offer more affordable aftermarket options.

At Affordable Security Locksmith And Alarm, we help Phoenix drivers make smart decisions based on their vehicle, budget, and security needs. Not sure which type of key is right for you? Learn more about our full car key replacement and programming options available throughout the Valley.

Let’s break down the difference between OEM and aftermarket car keys—and whether it’s worth paying extra for the dealership’s version.

What Are OEM Car Keys?

OEM keys are produced by or for your vehicle’s manufacturer. These are the same keys you’d get from the dealership.

Pros:

  • Guaranteed compatibility
  • Factory quality and branding
  • Works seamlessly with your car’s systems
  • Covered by manufacturer warranties

Cons:

  • Expensive (often $250–$600+)
  • Must be ordered from the dealer
  • May require towing to program at dealership
  • Long wait times for some models

What Are Aftermarket Car Keys?

Aftermarket keys are third-party keys made to match the specs of OEM keys—but sold and programmed by locksmiths or auto shops.

Pros:

  • More affordable (typically 30–60% less)
  • Available on demand from mobile locksmiths
  • Can be cut and programmed on-site
  • Many are nearly identical in performance

Cons:

  • Quality can vary depending on the supplier
  • Some advanced features (e.g., proximity start) may not be supported
  • May not include vehicle branding (logo, buttons, etc.)

We only use high-quality, locksmith-grade aftermarket keys—not the cheap plastic ones sold online.

Can Aftermarket Keys Be Programmed to Your Car?

Yes. In fact, we program aftermarket keys for:

  • Ford
  • Chevy
  • Toyota
  • Honda
  • Nissan
  • Dodge
  • Hyundai
  • Kia
  • BMW, Audi, and other luxury brands

We use diagnostic equipment to ensure each key communicates properly with your vehicle’s security system.

Are Aftermarket Keys Safe?

When provided and programmed by a licensed locksmith, aftermarket keys are:

  • Encrypted
  • Compatible with your car’s immobilizer system
  • Tested for performance and durability

Cheap, unprogrammed keys from Amazon or eBay? Not so much. Those can fail, cause system errors, or simply not work at all.

When Should You Choose OEM Instead?

  • If your vehicle is under warranty and the dealer requires OEM parts
  • You want the original logo on your fob or remote
  • Your car requires advanced proprietary programming (some luxury models)

Otherwise, high-grade aftermarket keys are a smart choice for most drivers.

What About Push-to-Start Keys and Smart Fobs?

We provide both OEM and aftermarket versions of:

  • Smart key fobs
  • Remote start keys
  • Proximity fobs
  • Flip keys
  • Remote entry transmitters

We’ll let you know the best option based on your vehicle and budget.

What Does It Cost?

In Phoenix, typical costs are:

  • OEM key from dealership: $250–$600
  • Aftermarket key from locksmith: $90–$250
  • Programming only (your key): $60–$120
  • Luxury/proximity key programming: $180–$400

We’ll always give you a flat quote upfront—no hidden fees.
