Keyless entry into vehicles has become a common feature in automotive technology in the last few years. Your car’s trunk, windows, and other features can be accessed with the push of a button with one of these keyless remote fobs.
This function has numerous advantages, but what happens if the battery in your keyless remote control runs out? It’s possible that you’ll find yourself in a precarious position.
If the battery in your keyless vehicle remote has died, there are a few things you may do to quickly regain access to your vehicle. To save you money at the mechanic, we’ve also included some useful information about battery changes.
What To Do When Your Keyless Remote Battery Is Low
When the battery on your key fob runs low, you might be perplexed as to what happens. It’s not uncommon to discover that your car’s remote key fob contains a security chip that allows you to access your vehicle even if the battery is dead or critically low.
As a last resort, place your key fob as close to your vehicle as feasible in order to start the vehicle.
However, if you wait too long, you may find yourself trapped and without access to your vehicle if this alternative doesn’t work out.
Fortunately, most keyless access systems come with a feature that prevents you from being locked out of your car. The battery life of the keyless remote fob can be monitored by sophisticated electronic configurations.
In addition, the dashboard keyless remote battery low light will be activated, making it impossible to use the keyless fobs features. To avoid further problems, you should replace the batteries as soon as possible if you find yourself in this situation.
Gaining Access
In the event that you have neglected to replace the batteries in your key fobs, you may find yourself unable to get into your vehicle or start the motor. If you find yourself stranded in your car and unable to get in or start it, we’ve compiled a list of possible options.
Battery Replacement
It’s a little more obvious, but changing the battery in your key fob can solve your access problem for roughly $5, and you can do it yourself with a screwdriver. Using a penny or a small screwdriver, you can pry open the battery cover on your fob key to get at the battery.
Key fob batteries look like silver buttons with numerals on them that indicate the sort of battery they are. Keep your key fob trouble-free by using the same type of battery every time you replace it.
Remote Application Unlocking
If you lose your key fob, you may be able to obtain entry to your vehicle using a pre-programmed PIN that comes standard on many vehicle models. Here are a few examples of what I’m talking about.
- AUDI has its myAudi App where you can access remote unlocking services if your key fob has died.
- BMW offers remote unlocking via their Connected Drive Programme on their website.
- FORD models from 2017 and 2018 may be equipped with SYNC Connect, but models from 2018 onwards will have the FordPass application access that gives you access to a range of features for your vehicle without the use of the key fob.
- HONDA newer models will gain a free trial period to their HondaLink application which features keyless entry and 24-hour roadside assistance from almost anywhere.
- NISSAN offers owners remote access via their Nissan Connect application or web portal.
Many other vehicle types offer comparable services and typically come with their own applications for these and other functions. For more information, contact the manufacturer of your car.
Hidden Key
Your fob may have a secret key if the preceding procedures are unavailable to you. It’s possible to bypass your keyless entry fob entirely if your fob is covered in leather. Simply remove the leather jacket and pull a little catch to reveal a mechanical key.
Starting Your Vehicle
Once you get into your car, it’s typically very simple to start it. In many cases, the system is set up to work even if the key fob remote isn’t working, and there are backups stored in the key fob itself.
There are several times when a plastic cap can be removed from the steering column to reveal a secret key slot.
If your car is equipped with push START technology, a backup system is likely already in place to ensure smooth starting in this case. This should work if you press the START button with your key fob.
