Review: Remote Key Fob Replacement Compatible with 2017 Ford Explorer

Losing your car keys is an immediate headache, especially when looking for a 2017 ford explorer key fob replacement that doesn’t cost a fortune at the dealership. I recently tested the Vailikey Smart Key Fob, a 5-button alternative designed to provide the same functionality as the original equipment at a fraction of the price. Whether you need a spare for your Ford Edge or a replacement for your Mustang, this unit comes fully loaded with the necessary electronics and batteries to get you back on the road. It is a specialized solution for those who value both performance and affordability.

Section 1: Overview of the Vailikey Smart Key Fob

When I first started looking for a budget-friendly remote, I was skeptical of the low $31.99 price point. However, the Vailikey Smart Key Fob stands out because it isn’t just a hollow plastic shell; it is a complete, fully-functional electronic unit. With a 3.8-star rating from over 135 reviews, it has established itself as a go-to option for Ford and Lincoln owners who want to avoid the $200+ markups typically found at local service centers.

In my experience, the build quality feels surprisingly robust. It mimics the weight and tactile response of the OEM (Original Equipment Manufacturer) remote, which is essential for a device you carry every day. This specific model, identified by part number 164-R7989, is engineered to handle the smart proximity features of modern Ford vehicles, including remote start and trunk release. It serves as a comprehensive bridge between high-end dealership parts and DIY-friendly hardware, provided you are prepared for the technical steps involved in the setup.

Section 2: Key Features and Compatibility Specifications

Full Internal Electronics and Battery Included

One of the biggest advantages I found is that this unit arrives completely assembled. Unlike some replacements that require you to swap motherboards from an old remote, this 2017 ford explorer key fob replacement includes the circuit board, transponder chip, and a fresh battery right out of the box. This ensures that you aren’t dealing with mismatched internal components that could lead to signal failure.

Comprehensive FCC ID Matching

To ensure a seamless sync with your vehicle’s computer, this fob is strictly compatible with FCC ID: M3N-A2C31243300. I noticed that it covers a wide range of popular part numbers, including 5923896 and 164-R8119, making it a versatile choice for various production years. Before purchasing, I recommend double-checking your current remote’s internal ID to ensure this 2017 ford explorer key fob replacement is the correct frequency for your specific trim level.

Pre-Tested Quality Standards

Vailikey claims that each smart key is pre-tested to ensure the electronics are transmitting correctly before they are shipped to customers. In my testing, the signal strength was consistent with the original fob, allowing for long-range locking and unlocking without lag. This level of quality control is reassuring when you are relying on the device for daily vehicle access and security.

Extended Vehicle Versatility

While I focused on the Explorer, this remote is a “jack of all trades” for the Ford and Lincoln ecosystem. It works flawlessly with the Ford Edge (2015-2017), Mustang (2015-2017), and Fusion (2013-2016), as well as several Lincoln MKZ and MKC models. Having one remote that spans multiple platforms makes it much easier to find the exact 2017 ford explorer key fob replacement you need without scouring through hundreds of different listings.

Twelve-Month Technical Support

The brand offers a 12-month technical support window, which provides a significant safety net for the user. If you run into issues during the pairing process or if the battery life isn’t meeting expectations, having a 24-hour response guarantee from the manufacturer adds a layer of confidence. I appreciate when a company stands behind their electronics, especially with aftermarket automotive parts.

Section 3: Pros and Cons: What to Expect

Choosing an aftermarket remote is always a balance between cost and convenience. Based on my hands-on time with the Vailikey unit, here is an honest breakdown of the strengths and weaknesses you should anticipate before hitting the buy button.

• ✅ Excellent Value: At $31.99, it is significantly cheaper than sourcing an OEM part from a Ford dealer.
• ✅ Complete Package: Includes the battery and all internal electronics, saving you the hassle of buying parts separately.
• ✅ OEM Feel: The plastic casing and button tension feel very close to the original 2017 ford explorer key fob replacement.
• ✅ Remote Start Support: The 5-button configuration fully supports remote start, panic, and trunk release functions.
• ✅ Responsive Support: The 12-month technical assistance offers peace of mind for those new to key programming.
• ✅ Wide Compatibility: Works across a variety of Ford and Lincoln models from 2013 to 2019.

• ❌ Complex Programming: This is not a “plug and play” device; it requires a specific sequence or professional equipment to pair.
• ❌ Locksmith Costs: Unless you have two working original keys, you will likely need to pay a professional for programming, which adds to the total cost.
• ❌ Vague Instructions: The included documentation can be a bit thin, requiring some YouTube research for your specific car model.

Section 4: Performance and Real-World Programming Experience

When I tested this replacement fob on a 2017 Explorer, the performance exceeded my expectations for a third-party unit, though it requires a specific set of circumstances to be truly “plug-and-play.” Here is how it fared in various real-world scenarios.

The DIY Programming Attempt

I attempted the DIY programming method using the “two-key” sequence. Since I had two original working keys, I was able to enter the car’s programming mode via the center console backup slot. The car recognized the new fob within seconds. However, users should be aware that if you only have one working key, you will not be able to do this yourself; you will need a locksmith with an OBDII programmer.

Range and Signal Strength

One of my primary concerns was the transmitter range. I tested the remote start and lock functions from approximately 60 feet away with moderate obstructions. The signal was consistent and the vehicle responded without delay. While it may not have the 100-foot-plus reach of a factory OEM remote, it is more than sufficient for pre-heating your car from your front door.

Long-Term Button Response

After a week of heavy use, the buttons maintained a satisfying “click” feel. Some cheap replacements tend to feel mushy or get stuck, but the internal membrane on this unit seems well-constructed. The proximity entry (Smart Key) feature worked flawlessly, unlocking the doors as soon as I touched the handle with the fob in my pocket.

Section 5: Who Should Buy This Replacement Fob?

This replacement is an excellent solution for specific types of owners, but it isn’t a universal “fix-all” for every situation.

• The “Two-Key” Prepared Owner: If you currently have two working fobs and want a third for a spouse or teenager, this is a no-brainer. You can program it yourself in minutes and save hundreds of dollars.
• The Budget-Conscious Commuter: For those who refuse to pay the $250-$400 dealer markup, this $31.99 unit provides 95% of the OEM experience for a fraction of the cost.
• The Used Car Seller: If you are selling your Ford and want to provide a second key to increase the resale value, this is an affordable way to complete the set.

Who should NOT buy this? If you have lost all your keys, or if you only have one key and are not willing to pay a locksmith for the labor of programming, this hardware alone won’t help you start your car.

Section 6: Frequently Asked Questions (FAQs)

Does this fob come with a battery included?

Yes, the unit comes pre-installed with a CR2032 battery. I recommend checking the battery seated position before programming, as vibration during shipping can sometimes shift it.

Can I program this 2017 ford explorer key fob replacement if I only have one working key?

No. Ford’s security system requires two unique, already-programmed keys to authorize a third key via the onboard DIY method. If you only have one key, you must take the fob to a locksmith or dealer to be programmed via the OBDII port.

Will the emergency key blade work?

The unit includes an uncut internal emergency blade. You will need to take this to a locksmith or a hardware store with a laser-cutting machine to match your vehicle’s physical lock cylinder.

Is this an official Ford OEM part?

No, this is a high-quality aftermarket replacement. While it looks and functions like the original, it does not feature the Ford or Lincoln logo on the back casing.

What is the frequency of this remote?

This specific 2017 ford explorer key fob replacement operates on a 902 MHz frequency, which is standard for the 164-R7989 smart key system.

What should I do if the car doesn’t recognize the fob?

First, ensure the battery is fresh and the polarities are correct. Second, make sure you are placing the fob in the correct “programming slot” (usually located in the center console or under the cup holder rubber mat).

Section 7: Final Verdict: Is It Worth It?

With a rating of 3.8 stars, this replacement fob occupies the “sweet spot” of value and functionality. While the setup process can be a hurdle for those with only one original key, the hardware itself is robust and reliable once synced. For anyone looking for a 2017 ford explorer key fob replacement, this unit offers a significant upgrade over the astronomical prices found at the dealership. If you have your two keys ready, this is a five-star value; for everyone else, it remains a solid four-star alternative to OEM parts. Highly recommended for proactive owners.
