2020 Toyota RAV4 Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

Unfortunately, the 2020 Toyota RAV4 does not support DIY on-board programming for its smart key fob. This is due to the advanced security system that requires a specialized scan tool (Toyota Techstream or equivalent) to program new key fobs to the vehicle's immobilizer system.

This means that programming will need to be performed by a Toyota dealership or a qualified automotive locksmith.

Battery replacement

Replacing the battery in your 2020 Toyota RAV4 key fob is a straightforward process:

1. Locate the small release button or switch on the side of the key fob and slide or press it to release the emergency key blade. Pull the key blade out.
2. With the emergency key blade removed, you'll see a small slot or notch. Use a flathead screwdriver or a coin to gently pry open the two halves of the key fob casing.
3. Carefully separate the two halves. You'll see the circuit board and the CR2032 coin cell battery.
4. Note the orientation of the old battery (usually positive side up). Gently pry out the old battery.
5. Insert the new CR2032 battery with the positive (+) side facing up.
6. Carefully snap the two halves of the key fob back together, ensuring they are securely closed.
7. Reinsert the emergency key blade until it clicks into place.

Where to buy a replacement fob

When considering where to purchase a replacement key fob for your 2020 Toyota RAV4, you have several options, each with pros and cons:

• Toyota Dealership:
  • Pros: Guaranteed genuine OEM part, expert programming, and support for any warranty issues.
  • Cons: Most expensive option. Expect to pay anywhere from $300 to $500+ for the fob and programming.
• Automotive Locksmith:
  • Pros: Often more affordable than a dealership, can provide and program OEM or high-quality aftermarket fobs, and many offer mobile services.
  • Cons: Quality of aftermarket fobs can vary, so ensure the locksmith uses reputable brands. Cost typically ranges from $250 to $400.
• Online Retailers (e.g., Amazon, eBay):
  • Pros: Potentially the cheapest option for the physical fob itself.
  • Cons: You'll still need to pay for programming separately, and there's a risk of purchasing counterfeit or incompatible fobs. Programming costs will be in addition to the fob purchase.

If on-board programming isn't supported

As mentioned, the 2020 Toyota RAV4 requires a specialized scan tool for programming. This means you'll need to factor in the cost of professional programming, whether from a dealership or a locksmith. The key fob also contains an immobilizer transponder (typically a Texas Instruments DST-AES chip, integrated into the remote itself) which must be programmed to the vehicle to allow it to start. Simply cutting the emergency key blade is not enough; the electronic components need to be electronically paired with your vehicle
