Keyless remotes contain a short-range radio transmitter, and must be within a certain range, usually 5–20 meters, of the car to work.
The vast majority of these systems are one-way with limited range. The remote sends a signal to the car, but the car does not send a signal back. They also don`t work more than about 50 feet away. Keyless ignition works in the same way and requires the same fob.
Most key finders should have a range of anywhere between 150.0 and 200.0 ft. for short-tracking purposes. Key finders that rely upon Bluetooth should also be able to provide a general location for your item via a smart device.
Keyless entry is considered an active RFID system, because pushing the button sends out the code, instead of receiving it. The immobilizer chips in the ignition keys that lock out car thieves are also active. Keyless ignition is defined as a passive RFID system.
The button will only operate when the smart key is within 0.7~1 m (28~40 in) from the driver side door handle. If you want to make sure that a door has locked or not, you should check the door lock button inside the vehicle or pull the driver side door handle.
When at home, storing keys in a metal-lined “Faraday box” or pouch will block the signal being sent out from your key fob, thus preventing thieves from being able to capture it.
What happens when the key fob battery is low? Typically, a key fob with a low battery starts exhibiting some or all of the following symptoms: The fob may become less responsive or unresponsive over time. It may not lock/unlock your car easily and may start losing its range.
Chances of theft

The layers of security in a keyless system are strong, but hackers are constantly developing newer ways to steal cars. Key programming tools are easily available both online and off, and in the wrong hands, one could reprogram a blank fob to your car`s transponder, thus compromising security.

Tile Pro (2022)

And that`s why the Tile Pro remains our pick for the best key finder you can buy. It`s got the best range of any key finder we`ve tested with a good, loud alarm. A two-way find feature helps you locate your phone if you`ve misplaced it just by pressing the Tile logo twice on the key finder.

In general, keyless entry fobs have a range of five to six metres, so one of the scanner units has to be no farther than this from the fob.
Are keyless entry door locks safe? Yes, keyless entry door locks are safe. They are more secure than traditional locks because it is much harder for someone to guess your code than it is for them to pick a traditional lock.
Since keyless ignition doesn`t automatically turn off when you leave the car with the fob or smart key, you`ll need to put the car in park and press the stop button first.
Keyless theft (otherwise known as relay theft) is relatively simple; all it requires is two small boxes of electronics, which thieves can use to open your car in as little as 60 seconds. Crooks will typically work in pairs to commit relay theft, with one holding a relay amplifier, and the other a relay transmitter.
When your car keys are within range (about one metre / three feet) then you can grip the handle to unlock, or touch the button on the handle to lock the car. If you don`t open a door within 2 minutes of unlocking, they automatically lock again.
In general, keyless entry fobs have a range of five to six metres, so one of the scanner units has to be no farther than this from the fob.

It won`t, only when you turn off the engine and when starting it would say “key not detected”. So long as the engine is on if you like throw the key away everything would be fine, just don`t turn the engine off..

Relevant Questions and Answers :

the most relevant questions and answers related to your specific issue

Need help getting a keyless entry for my car
ANSWER : An aftermarket keyless entry system may or may not be required. If the vehicle is equipped with original equipment electronic door locks, the key fob typically should be able to be programmed to work with your keyless entry. The car may have a limit on how many key fobs are able to be programmed to the vehicle. If the vehicle is equipped with manual door locks and you wanted to use a key fob, the car would need electronic door locks installed to be able to use the fob. I recommend having the vehicle looked at further by a locksmith or technician to have this issue resolved.

What can I do if the remote keyless entry remote only works up close?
ANSWER : The remote keyless entry system is not only a great convenience, but it increases vehicle security by being able to lock or unlock the doors from a distance. If the range of the remote decreases, there are a few points to check out:

First, see how far away you can get from the vehicle with the remote remaining functional. This will show you the extent of the range.
Next, make sure that there are no objects blocking the vehicle from the remote.
If the range is poor even when the space between the remote and vehicle is clear, then the battery needs to be checked and possibly replaced.
If the battery was not the problem, call a dealer about getting a replacement remote.

What is the range of the keyless entry remote?
ANSWER : The remote that locks and unlocks the doors can also be used to set off the vehicle’s alarm in the event of an emergency. The remote has a range of around 200 feet, depending on battery strength and line of sight.

In a keyless entry car, can you also have an alarm say auto watch alarm system installed?
ANSWER : Hello. From what you describe it would appear that the aftermarket alarm system may be having an issue. If the alarm has done this since it was installed then it may be possible that it is wired improperly, or that there is an issue with the alarm system control module. It may be possible that the two alarm systems are interfering with each other somehow, perhaps due to an issue with the transponders or remotes. I would recommend referring to the alarm system manufacturer, or the shop or technician that installed the alarm for more specific support or instructions.

Can I add keyless entry to a car?
ANSWER : Some economy late model vehicles, like the Sentra you are considering, are not equipped with keyless entry. I highly doubt the owner lost the remotes. It is possible to buy an aftermarket keyless entry system and have it installed.

What does the keyless entry remote do?
ANSWER : The keyless entry remote should always be kept with the keys for the vehicle as well. There are 3-4 buttons on the remote depending on the trim package.

The button with a closed lock symbol will lock all of the doors of the vehicle. Pressing the button twice within 3 seconds will cause the vehicle to make a chirping sound. If the vehicle has an anti-theft alarm system, this button will arm the system.
The button with an open lock symbol unlocks the doors. When pressed once, the driver’s door will unlock. If the button is pressed again or pressed while the driver’s door is already unlocked, then the remaining doors will open. This button disarms the theft deterrent system as well.
The button with the trumpet symbol on it will make the turn signals flash and will cause the horn to honk 3 times when pressed. In case of an emergency, the button can be pressed and held for over 2 seconds to activate the alarm system.
If the vehicle is equipped with remote starting, there will be a 4th button on the remote with a curved arrow on it. Pressing this button will start the engine remotely.

How do I lock the doors with the remote keyless entry system?

How do I program a new remote keyless entry (RKE) transmitter with a recognized transmitter?
ANSWER : If your vehicle has no remote keyless entry (RKE) transmitters that are currently programmed, then you will need to program all of your RKE transmitters. This process can take a while, but is easy to do if you follow these instructions:

Make sure that your vehicle is turned off, and that you have all of the transmitters that you will be programming.
Extend the key from one of the RKE transmitters by pressing the button at the top of the transmitter.
Insert the key into the door lock on the outside of the driver’s side door, and turn the key into the unlock position five times, within a span of 10 seconds. After doing this, the Driver Information Center (DIC) will display the words “Remote Learn Pending, Please Wait.”
After about 10 minutes, the DIC will switch to the words “press engine start button to learn.” Following this prompt, press the ignition button. The DIC will then return to the words REMOTE LEARN PENDING, PLEASE WAIT.
Repeat step 4 two times, so that the vehicle has cycled through the ignition stage three times. At this point, all previously programmed transmitters will no longer work. That way, if a transmitter has been lost or stolen, it cannot be used on your vehicle any more. The DIC should now display the words READY FOR REMOTE #1.
Locate the RKE transmitter outlet, which is on the center console, directly next to the power outlet. Remove the plastic trim from the transmitter outlet, revealing the transmitter slot.
Place the RKE transmitter key that had been used in the driver’s side door into the transmitter outlet slot.
Press the ignition button. This will program the RKE transmitter.
When the DIC displays that the transmitter has been programmed, remove the transmitter and press the unlock button on it.
Repeat steps 7-9 with the remaining transmitters that you wish to program.
Press and hold the ignition button for 10 seconds, which will quit out of programming mode.
Place the plastic trim back on the transmitter outlet slot.
All of the RKE transmitters are now programmed.
