Transponder technology is now widely used in vehicles nowadays and is seen in many locations that require security clearance. The transponder chip in modern vehicle keys is activated when the key is inserted into the ignition by the radio frequency signal sent from the ignition barrel.
When the signal received from the chip is verified as accurate by the vehicle’s ECU, the immobilizer is turned off and the engine is started.

How can a key fob with a push-button start be programmed?
You may be able to program a keyless ignition fob for vehicles with a push-button starter in some circumstances. Even though it’s far from foolproof, it’s worth a shot before paying a dealer to program it for you.
- Get into the driver’s seat and close the door behind you while holding the key fob in your hand. Prepare to place one hand on the key fob and the other on the start button of the car. You’ll need to work rapidly, just like the processes mentioned before, so get ready for that.
- When you’re ready, quickly hit the start button on your car 15 times, with no more than two seconds passing between each try. Remember, you’re not actually trying to start the engine while doing this, so keep your foot off the brake.
- Press the lock button on your fob after the fifteenth button press. The car doors will lock and the fob will be fully functional if the pairing process was completed. If the attempt failed, it could be worthwhile to try it again to determine if there was a mistake in the first attempt. The timing of this strategy can be a little tricky and challenging to master the first time.
After changing the battery, is the Toyota key fob required to be reprogrammed?
A remote key fob needs to be associated with your vehicle particularly in order to be secure.
This stops people who drive the same make and model of automobile as you from using their remote to access your car. You’ll need to reprogram the fob if changing the batteries has erased this connection or if it was somehow disrupted in order for it to once again recognize your automobile.

Can a key fob be programmed without visiting the dealership?
“Due to the pricey programming equipment needed, a new-car dealer will typically be your best option if you need a replacement key fob for a vehicle that was manufactured within the last five years, according to John Ibbotson, CR’s chief mechanic.
We discovered from Audi and Subaru dealers that some key fobs won’t function with aftermarket key fobs, despite the temptation to go for a less expensive one online.
“According to a service advisor at Hoffman Audi of East Hartford, Connecticut, if you need a new key fob for your Audi, it must come from us. The key fob has a built-in security chip that cannot be modified to work with another Audi. A new aftermarket Audi key fob cannot be purchased online because of the requirement for this chip.” He claimed that the car’s security now depends heavily on the fob. We were informed that the typical cost of replacing an Audi key fob, including programming, is $500.
This applies to all European vehicles, not just Audi. Because the manufacturer can only program the digital key encryption in a small number of exclusive stores in North America, they nearly always require the customer to see a dealer, said Yu of CR.
Other merchants we contacted, such a Lexus dealership and a Chrysler/Jeep/Dodge dealership, stated they don’t mind attempting to program aftermarket fobs if the buyer requests it as long as the customer is aware of the dangers.
A service advisor at a Lexus dealer told us that they were reluctant to work with aftermarket key fobs.
If we try to program it and it doesn’t function, we still have to charge them for our labor even if we can’t guarantee components or labor.
Fortunately, even if you have to visit a dealer, the procedure is quick. Key-fob programming, according to the majority of the dealers we spoke with, usually only requires 15 to 30 minutes, and the entire process, including creating the mechanical replacement key, rarely lasts longer than an hour.
Even if they handle everything for you, going to the dealer doesn’t have to be expensive. Even with European brands, this held true. A replacement fob with a laser-cut key and programming for CR’s 2015 VW Jetta would cost roughly $225, according to a local Volkswagen dealer with whom we spoke.
Customers can save money on programming with some companies, like Chevrolet. For instance, a Chevrolet official informed us that the key-fob programming does not need to be done at the dealership and that General Motors key fobs are on the more affordable side ($147.98 for a 2019 Chevrolet Malibu with keyless entry, push-button start, and remote start).
“The vehicle must be present, but the programming process is outlined in the owner’s manual, he added.
Be advised that most customer-programmable key fobs, regardless of brand, require two active, functional keys in order to program a third new key without visiting the dealer, according to Yu.

Can a used Toyota key fob be reprogrammed to operate a another vehicle?
I’m here. As long as the key is the same for each vehicle, you can reprogram a key fob to work with that vehicle. In this situation, if the key can open the doors, you would need to take the following actions:
- The key fob’s battery should be removed and then replaced (unless you put in a new battery)
- After unplugging the vehicle’s battery wires, wait 30 seconds, then reconnect them (reset computer).
- Turn the key to the ON position after inserting it into the ignition.
- In the OFF position, turn the key.
- Locking the door simultaneously with your hand and the remote requires turning the key to the ON position.
- While simultaneously using the remote and your hand to unlock the door, turn the key to the ON position.
- Remove the ignition switch’s key.
- the driver door with the key.
- Push the lock and unlock buttons on the key fob simultaneously with locking and unlocking the door with the key – (do this 3 times).
- Try using the remote to unlock the doors while the door is closed after taking the key out of the lock.
- Put the key in the ignition switch and attempt to start the engine if the doors will lock.
After completing these procedures, the key fob has been successfully reprogrammed to your car if the engine starts. If the key does not lock the doors or start the engine, it may be completely different, and you will need to get a new key. Seek out a specialist, like one from Your Mechanic, if you require more help with your keyless entry system.
