2016 Chevrolet Suburban Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2016 Chevrolet Suburban does not support DIY on-board programming for new key fobs. The vehicle's sophisticated security system, which includes an immobilizer, requires specialized diagnostic equipment to program new key fobs. This means a trip to an authorized Chevrolet dealer or a professional automotive locksmith is necessary.

Attempting to program a new key fob yourself without the proper tools can result in the fob not working or, in some cases, the vehicle's immobilizer system locking you out. This is a security measure designed to prevent theft.

Battery replacement

Replacing the battery in your 2016 Chevrolet Suburban key fob is a straightforward process:

1. Locate the small release button or tab on the side or bottom of the key fob. Press or slide this to release the integrated key blade.
2. With the key blade removed, you should see a small slot or indentation along the seam of the fob casing. Use a small flathead screwdriver or a coin to carefully pry the two halves of the fob apart.
3. Once opened, you will see the circuit board and the CR2032 coin cell battery. Note the orientation of the old battery (usually positive (+) side up).
4. Gently remove the old battery and insert the new CR2032 battery, ensuring the positive (+) side is facing the correct direction.
5. Align the two halves of the key fob casing and press them firmly together until they snap securely into place.
6. Reinsert the key blade.

Test the functions of your key fob (lock, unlock, remote start, etc.) to ensure it's working correctly.

Where to buy a replacement fob

When it comes to purchasing a replacement key fob for your 2016 Chevrolet Suburban, you have a few options, each with its own pros and cons:

• Chevrolet Dealership:

  • Pros: Guaranteed genuine OEM part, often comes with programming services included, expert technicians.
  • Cons: Most expensive option. Expect to pay between $200-$350 for the fob and programming.

• Automotive Locksmith:

  • Pros: Often more affordable than a dealership, many locksmiths offer mobile services, can cut and program keys on-site, may offer OEM or high-quality aftermarket options.
  • Cons: Quality can vary depending on the locksmith. Prices typically range from $150-$280 for fob and programming.

• Online Retailers (e.g., Amazon, eBay):

  • Pros: Potentially the cheapest option for the fob itself.
  • Cons: You're only buying the physical fob; you'll still need to pay for cutting and programming separately. There's also a risk of purchasing a counterfeit or incompatible fob. Prices for the fob alone can be as low as $30-$80, but remember to factor in programming costs (which will be similar to locksmith or dealer rates).

Always ensure any aftermarket fob is compatible with FCC ID OHT01060512 to guarantee functionality.

If on-board programming isn't supported

As mentioned, your 2016 Chevrolet Suburban requires professional programming due to its advanced immobilizer system. This system uses a transponder chip embedded in the key fob that communicates with your vehicle's computer. Without proper synchronization, the car simply won't start, even if you can manually unlock the doors.

The cost for programming will vary based on your location and the service provider (dealer vs. locksmith). Generally, you can expect to pay anywhere from $70 to $150 for the programming service alone. This is in addition to the cost of the replacement key fob itself. Be sure to ask for an all-inclusive quote when contacting a locksmith or dealer.
