Whether you are a weekend DIYer or an off-road enthusiast, understanding your remote system is essential for vehicle security. Let’s dive into the technical details and practical solutions for your F-150 entry system.
Identifying Your Specific 2020 ford f150 key fob Type
Before you attempt any repairs or buy a replacement, you must identify which remote your truck uses. Ford offered several variations for the 2020 model year depending on the trim level, such as the XL, XLT, Lariat, or Raptor.
The most common version is the Intelligent Access (IA) fob. This is a “pebble” shaped remote used for push-button start vehicles. It typically features four or five buttons, including lock, unlock, remote start, and a power tailgate release.
The second type is the Integrated Keyhead Transmitter. This looks like a traditional key with buttons built into the handle. It is usually found on base trims like the XL and some XLT models that still use a physical ignition cylinder.
Check the back of your remote for the FCC ID number. This small string of text ensures you buy the correct frequency transmitter if you need a spare. Matching the frequency is critical because a remote for a different year might look identical but will not communicate with your truck.
The Hidden Emergency Key
Many owners do not realize that the Intelligent Access remote contains a physical key blade. You can find a small release switch on the back or side of the 2020 ford f150 key fob casing. Sliding this switch allows you to pull out a mechanical key.
This mechanical key is your lifeline if the truck battery or the remote battery dies. You can use it to manually unlock the driver’s side door. Once inside, you can use the backup slot to start the engine, which we will cover later in this guide.
How to Replace the Battery in Your F-150 Remote
A weak battery is the most frequent cause of “key not detected” errors. You might notice the range of your remote decreasing or the truck failing to respond unless you are standing right next to the door.
Most 2020 F-150 Intelligent Access remotes use a CR2450 coin cell battery. The flip-key style remotes typically use a CR2032 battery. Always verify the battery type printed on the old cell before installing a new one.
- Remove the emergency key blade from the bottom of the remote.
- Locate the small slot in the middle of the remote housing where the key was stored.
- Insert a flathead screwdriver or the tip of the key into the slot and gently twist.
- The two halves of the plastic shell will pop apart, revealing the circuit board and battery.
- Use a small tool to lift the old battery out, being careful not to bend the metal contact tabs.
When installing the new battery, ensure the positive (+) side is facing the correct direction. Avoid touching the flat surfaces of the new battery with your bare fingers, as skin oils can cause corrosion over time. Wipe the battery with a clean cloth before snapping the shell back together.
Mastering Your 2020 ford f150 key fob: A Complete Maintenance Guide
Maintaining your remote is about more than just changing batteries; it involves understanding how the hardware interacts with the truck’s computer. The 2020 ford f150 key fob communicates via Radio Frequency (RF) signals that can occasionally be disrupted.
If you frequent off-road areas with high-voltage power lines or use aftermarket electronics like dashcams, you might experience signal interference. These devices can emit “noise” that drowns out the remote’s signal. If your remote acts up only in specific locations, interference is likely the culprit.
Another maintenance tip is to inspect the internal buttons. Over time, dust and pocket lint can migrate inside the shell. If a button feels “mushy” or requires a hard press, open the shell and clean the contact points with a Q-tip and a tiny drop of isopropyl alcohol.
Protecting the Fob from the Elements
For those who use their F-150 for camping or work, the remote is exposed to moisture and drops. While the factory shells are durable, they are not waterproof. Consider using a silicone protective cover to add a layer of shock absorption and water resistance.
If you drop your remote in water, remove the battery immediately. Place the open shell in a bag with silica gel packets for 24 hours. Do not use a hairdryer, as excessive heat can damage the delicate microchips on the circuit board.
DIY Programming for New F-150 Remotes
You can program a new 2020 ford f150 key fob yourself, but there is a major catch. You must have two currently programmed and working keys to perform a DIY add. If you only have one key, you will need to visit a locksmith or a dealership with a scan tool.
This security measure prevents someone with temporary access to one key from quickly making a duplicate. If you have both original keys, follow these steps carefully. Timing is everything in this process, so read the steps through once before starting.
- Place the first programmed key in the backup slot (usually located under the cupholder rubber mat or in the center console).
- Press the Start/Stop button for one second (do not press the brake; you only want the ignition on).
- Wait five seconds, then press the Start/Stop button again to turn the ignition off.
- Remove the first key and insert the second programmed key into the slot within five seconds.
- Press the Start/Stop button for one second, wait five seconds, then turn it off and remove the second key.
- Insert the new, unprogrammed key into the slot and press the Start/Stop button.
If successful, the doors will cycle (lock and unlock), and the information display will confirm the new key is programmed. If it fails, wait a few minutes and try again, ensuring your movements are quick and precise. This method works for the 2020 ford f150 key fob because the truck recognizes the “admin” status of the first two keys.
What if You Only Have One Key?
If you are down to your last remote, do not wait until you lose it. Programming a second key when you still have one is much cheaper than a “keys lost” scenario. A mobile automotive locksmith can usually program a new remote for about half the price of a dealership.
You can also use software like FORScan if you are a tech-savvy DIYer. This requires an OBDII adapter and a laptop. It allows you to access the truck’s PATS (Passive Anti-Theft System) to add keys, but it carries a risk if you are unfamiliar with automotive software.
Emergency Procedures: Starting Your F-150 with a Dead Fob
It is a common fear: you are miles away from civilization, and your remote battery dies. You can still start your truck. Ford designed a “backup slot” or “backup pocket” specifically for this situation.
The backup slot contains an induction coil that powers the chip inside your remote, even without a working battery. In the 2020 F-150, this slot is typically located at the bottom of the front cupholder. You will need to remove the rubber liner to see the key-shaped indentation.
In some trim levels, the slot is located inside the center console storage bin. Look for a small plastic pocket near the front wall of the console. Place your 2020 ford f150 key fob into this slot with the buttons facing up or toward the rear, depending on the specific pocket shape.
Once the remote is in the slot, press the brake pedal and hit the Start/Stop button as usual. The truck should recognize the transponder and fire up the engine. This allows you to drive home or to a store to buy a replacement battery.
Troubleshooting Common Remote Entry Issues
Sometimes the issue isn’t the battery or the programming. If your 2020 ford f150 key fob stops working suddenly, check the truck’s main battery first. A low vehicle battery can cause the Keyless Entry Module to go into a “sleep mode” to save power.
If the truck starts but the buttons don’t work, you might have a synchronization issue. This can happen if the buttons are pressed many times while out of range of the vehicle. Usually, starting the truck with the key in the backup slot will re-sync the rolling codes.
Check for blown fuses related to the Body Control Module (BCM). Consult your owner’s manual for the fuse box diagram. If the receiver inside the truck is not getting power, no amount of key programming will fix the problem.
The “Key Not Detected” Warning
If you see this message while driving, it usually means the remote has moved too far from the sensors or the battery is dying. However, it can also be caused by magnetic interference. Keep your remote away from your smartphone or large bunches of other keys.
If the message persists with a new battery, the internal antenna in the remote may have come loose. This often happens after a hard drop on concrete. In this case, the remote will likely need to be replaced entirely.
Where to Buy Replacement Remotes and Save Money
Buying a 2020 ford f150 key fob from a dealership can cost upwards of $300 to $500 including programming. Fortunately, there are more affordable avenues for the budget-conscious owner.
Online retailers offer “OEM-style” aftermarket remotes for a fraction of the cost. These look and function just like the original. However, be wary of extremely cheap remotes from unverified sources, as they often have poor signal range or fail after a few months.
Look for “Refurbished OEM” remotes. These are genuine Ford parts that have been cleaned and tested. They offer the best balance of reliability and price. Always ensure the listing specifies that the transponder chip is “unlocked” or “ready for programming.”
- Dealership: Most expensive, but guaranteed to work and includes a warranty.
- Automotive Locksmith: Mid-range price, often offers mobile service to your home.
- Online DIY: Cheapest option, but requires you to handle the programming yourself.
Frequently Asked Questions About 2020 ford f150 key fob
What battery does the 2020 F-150 key fob use?
The Intelligent Access (push-button start) remote uses a CR2450 battery. The standard flip-key remote typically uses a CR2032 battery. Always check the number on your current battery before buying a replacement.
Can I program a new key if I only have one working one?
No, the onboard DIY programming sequence requires two unique, already-programmed keys. If you only have one, you must use a locksmith or a dealership to add a second or third remote to the system.
Why does my truck say “No Key Detected” when the fob is in my pocket?
This is often caused by a weak battery in the remote or interference from a smartphone in the same pocket. Try placing the remote in the backup slot to see if the truck starts; if it does, replace the remote battery immediately.
How do I hide a spare key for off-roading?
For off-roaders, hiding a physical emergency key blade in a magnetic box under the frame is a common practice. However, do not hide the entire electronic 2020 ford f150 key fob inside the truck, as this may allow anyone to start the vehicle if they break a window.
Can I use a key fob from a 2018 or 2019 F-150?
Generally, yes, as long as the FCC ID and the button configuration match. The 2018-2020 models share the same architecture, but you must ensure the frequency (usually 315MHz or 902MHz) is identical.
Final Thoughts on Remote Maintenance
Taking care of your 2020 ford f150 key fob is a simple task that prevents major inconveniences. By keeping a spare battery in your glove box and knowing the location of your backup slot, you ensure that you are never truly stranded.
If you are planning a long trip or an off-road adventure, test your spare remote before you leave. It is much easier to deal with a programming issue in your driveway than in the middle of a national forest. Always prioritize high-quality batteries to avoid leaks and circuit damage.
Stay proactive with your truck’s security and maintenance. A little bit of technical knowledge goes a long way in keeping your F-150 ready for whatever the road throws at it. Stay safe and stay comfortable!
