2016 Scion iM Key Fob Guide: Decoding Programming, Costs, and Compatibility
This guide covers the essential details you must know before replacing the flip-key fob for your 2016 Scion iM, including programming requirements and how to verify compatibility.
- Professional programming by an automotive locksmith or dealer is mandatory; DIY programming is not possible for the 2016 Scion iM.
- Compatibility is critical: the replacement fob MUST have FCC ID HYQ12BFA and be for the 'H' chip system.
- Replacement is a two-part process: the new key blade must be professionally cut, and the electronic fob must be programmed to the car.
- Always try replacing the CR1620 battery first, as it's the most common and cheapest fix for an unresponsive fob.
Symptoms of a Failing 2016 Scion iM Key Fob
When a key fob begins to fail, it can manifest in several ways, ranging from a minor inconvenience to preventing the car from starting. Here are the most common symptoms:
- Unresponsive Buttons: The lock, unlock, or panic buttons work intermittently or not at all. This is often the first sign of failure.
- Reduced Signal Range: You have to be much closer to the vehicle than usual for the remote functions to work.
- Car Cranks But Won't Start: The engine will turn over but never fully start. This often indicates that the vehicle's immobilizer is not recognizing the transponder chip in the key.
- Starts and Immediately Stalls: The engine may fire up for a second or two before the immobilizer shuts it down.
- Flashing Security Light: A key or security symbol on the dashboard may blink rapidly when you try to start the car, signaling a transponder communication error.
- 'Key Not Detected' Message: The instrument cluster may display a warning that the key is not detected, even when it's inside the vehicle.
Pro Tip: Always replace the battery first. A weak or dead battery is the most common cause of fob issues and is the easiest and cheapest fix. The 2016 Scion iM fob requires one CR1620 battery.
Buying a Used 2016 Scion iM Fob/Remote
Purchasing a used OEM fob can be a cost-effective alternative to buying new from a dealer, but you must verify compatibility to avoid wasting money on a part that cannot be programmed to your car. Follow these guidelines for a successful purchase.
Verification Checklist:
- Match the FCC ID: The most critical step is to ensure the FCC ID on the back of the replacement fob is HYQ12BFA. A fob with a different FCC ID will not program to your vehicle.
- Confirm the 'H' Chip: The original key blade for this vehicle is stamped with a small letter 'H'. This indicates it uses a specific type of transponder chip (Texas ID 4D 'H' Chip). The replacement fob must be compatible with this system.
- Inspect the Case: Check the used fob for cracks, significant wear on the buttons, or signs that it has been pried open, which could indicate internal damage or water intrusion.
- Understand Blade Replacement: A used fob will come with a key blade that is already cut for another vehicle. This blade is useless for your car. You will need to purchase a new, uncut key blade (Keyway: LXP90) and have it cut by a locksmith to match your existing key or vehicle's locks.
Warning: While used OEM fobs for the Scion iM can be reprogrammed, some locksmiths may be hesitant to program customer-supplied used electronics. Always confirm with your chosen locksmith that they are willing and able to program a used fob you provide before you purchase it.
Programming and Key Cutting Requirements
Replacing the key fob for a 2016 Scion iM is a two-step process involving both cutting a new key blade and programming the electronics. This is not a do-it-yourself job.
The 2016 Scion iM does not have an onboard procedure for programming new keys. You must use a professional with specialized diagnostic tools, such as Toyota's Techstream software, to program both the remote functions (lock/unlock) and the immobilizer transponder chip to the vehicle's computer.
Who Can Program This Fob?
- Automotive Locksmiths: This is often the most convenient and cost-effective option. Most mobile locksmiths have the necessary equipment to cut the key and program the fob at your location.
- Toyota/Scion Dealerships: Dealers can always perform the programming, but they typically charge more for both the part and the labor. They may also refuse to program a key that was not purchased from them.
Known Issues, TSBs, and Recalls
The 2016 Scion iM has one safety recall (NHTSA ID: 16V286000), but it pertains to an accessory load-carrying capacity label and is unrelated to the key fob or vehicle electronics. There are no widespread, documented factory defects, technical service bulletins (TSBs), or recalls specifically concerning the key fob for this vehicle. Failures are typically due to normal wear and tear, battery depletion, or physical damage.

Frequently Asked Questions (FAQ)
Can I program a new 2016 Scion iM key fob myself?
No. The 2016 Scion iM does not support DIY or 'onboard' programming for new keys. You must have it professionally programmed by an automotive locksmith or a dealership using specialized equipment.
What does the 'H' stamp on my key blade mean?
The 'H' stamp indicates that your key uses a specific type of high-security transponder chip. It is crucial that any replacement key or fob is compatible with the 'H' chip system to ensure it can be programmed to start the vehicle.
Can I just replace the outer shell or case of my fob?
Yes. If your fob's electronics are still working but the case is broken or the buttons are worn out, you can purchase a replacement shell. You would then transfer the internal circuit board, transponder chip, and battery into the new shell. This does not require reprogramming, but you will still need to have the new key blade cut if the flip mechanism is part of the replacement shell.
What happens if my key fob battery dies? Can I still start the car?
Yes. If the fob battery is dead, you can still get in and start the car. Use the physical emergency key inside the fob to unlock the driver's door manually. To start the engine, hold the Scion logo on the key fob directly against the push-to-start button while you press the button with your foot on the brake. The car's immobilizer system can read the transponder chip at very close range even with a dead fob battery.
