Replacement Key Fob For 2017 Ford Explorer – A DIY Programming Guide
Need a spare or lost your only remote? This guide explains exactly how to identify, source, and program a replacement key fob for 2017 ford explorer models without needing an expensive trip to the dealership service center.
There is nothing quite as frustrating as realizing your key fob is dead or missing right when you are headed out for a weekend camping trip or a morning commute. If you are currently staring at a locked vehicle, don’t panic. Getting a replacement key fob for 2017 ford explorer units is a straightforward process that you can often handle yourself with the right parts and a little patience.
In this guide, we will walk through identifying your specific key type, where to buy reliable hardware, and the exact steps to sync your new remote to your SUV’s onboard computer. Whether you are a seasoned garage tinkerer or a first-time DIYer, you will find that managing your vehicle’s security access is well within your reach.
Understanding the Replacement Key Fob for 2017 Ford Explorer Options
Before you spend money on a new remote, you need to understand the hardware. The 2017 Ford Explorer typically uses an Intelligent Access push-to-start proximity remote. This device communicates with your SUV’s Restraints Control Module (RCM) and Body Control Module (BCM) via specific radio frequencies.
When searching for a replacement, always verify the FCC ID located on the back of your existing fob. Using the wrong frequency will prevent the vehicle from recognizing the signal, rendering the remote useless regardless of how well you follow the programming instructions.
OEM vs. Aftermarket Remotes
You generally have two choices: factory-original (OEM) parts or high-quality aftermarket alternatives. OEM fobs are often more expensive but offer the best build quality and long-term reliability.
Aftermarket options are budget-friendly and frequently work perfectly. If you choose the aftermarket route, look for vendors with high ratings and check for a return policy in case the internal transponder chip is faulty.
Pre-Programming Requirements and Safety Steps
Before attempting to pair a new remote, you must have at least two working keys already recognized by the vehicle. If you have lost all your keys, the DIY method will not work, and you will need to contact a mobile automotive locksmith or your local Ford dealership for security clearance.
Ensure your vehicle is parked in a safe, flat area. If you are doing this in a remote off-road setting, ensure your battery voltage is strong. A weak car battery can sometimes cause the programming mode to drop out before the sequence is complete.
Step-by-Step Programming Procedure
If you have your two original keys, you can usually add a third or fourth key using the onboard programming sequence. This procedure puts the car into a “learn” mode that accepts new signal codes from your new fob.
- Insert the first programmed key into the backup slot (usually located in the center console or under the steering column trim).
- Turn the ignition to the On position, wait for the dash lights to cycle, then turn it off.
- Repeat this process with your second working key within five seconds.
- Insert your new, unprogrammed key fob into the backup slot.
- Turn the ignition to On and wait for the door locks to cycle, confirming the new key is programmed.
Troubleshooting Common Programming Failures
Sometimes the car refuses to enter programming mode. This usually happens because the timing between the key insertions was too slow or the ignition was not held in the correct position long enough.
If the locks do not cycle, turn the vehicle completely off, wait thirty seconds, and try again. Ensure the emergency metal key blade is fully inserted into the lock cylinder during the process, as the vehicle needs to verify the physical key presence before accepting a new remote signal.
When to Call a Professional
If you have tried the sequence multiple times and the vehicle remains unresponsive, there may be a fault in the receiver module. In this case, stop the DIY attempt to avoid locking out your ignition system. A locksmith with specialized OBD-II diagnostic tools can often bypass these issues in minutes.
Maintaining Your Key Fob for Longevity
Once you have a working setup, protect your investment. Key fobs are sensitive electronic devices that hate moisture and high impact. If you are an off-roader or spend time near water, consider a silicone protective cover.
Replace the CR2032 coin battery every 18 to 24 months, even if the remote still works. Weak batteries can cause “intermittent signal” issues where you have to stand right next to the door to get the lock to trigger. Keep a spare battery in your glove box for emergencies.
Frequently Asked Questions About Replacement Key Fob for 2017 Ford Explorer
Can I program a new key if I only have one working key?
Unfortunately, no. The 2017 Ford Explorer system requires two recognized keys to initiate the self-programming mode. If you only have one, a dealership or a qualified locksmith will need to use a scan tool to add a new key.
Does the replacement fob come with the metal emergency key?
Most replacement fobs include a blank metal blade, but you will need to take it to a hardware store or locksmith to have it cut to match your door locks. Do not skip this step; if your battery dies, you will need that blade to gain entry to the cabin.
Why is my new key fob not starting the engine?
This usually indicates the transponder chip inside the fob was not successfully paired, even if the remote buttons work. Ensure you followed the “backup slot” steps correctly, as the car needs to read the chip specifically to authorize an engine start.
Are all 2017 Ford Explorer fobs interchangeable?
No. You must match the part number and FCC ID found on your original fob. Even if two remotes look identical on the outside, they may operate on different frequencies or utilize different security encryption.
Managing your vehicle’s security is an empowering skill that saves both time and money. By keeping a spare key in a safe place at home, you ensure that a simple lost remote never ruins your next adventure. Stay safe, keep your gear maintained, and enjoy the open road!
