“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.

How should a circuit board be cleaned?
Finding the proper solvent or chemical solution to thoroughly clean the circuit board without harming your delicate electronic components is crucial while learning how to clean electronic circuit boards. Electronic circuit boards shouldn’t often be cleaned with chemical solvents that have a high water content or slow evaporation rate since the high water content might cause the solvents to pool and expose the electronics to dangerously high amounts of moisture. Because of this, IPA, or isopropyl alcohol, is the best cleaning agent. IPA that is 99 percent pure has an extremely low water content and a rapid rate of evaporation. Without having to worry about pooling or residual solvent causing harm, IPA efficiently cleans in intricate places. High-quality IPA is a fantastic alternative if you’re looking for a cost-efficient and efficient solvent for cleaning electrical circuit boards.
How to Clean Electronic Circuit Boards with IPA:
- Gather Your Supplies: You’ll need cotton swabs, 99 percent isopropyl alcohol, and a small bowl to thoroughly clean your electronic circuit board.
- Clean the Board: First, fill your bowl with a tiny amount of isopropyl alcohol. To remove any extra solution, simply dip a cotton swab into the alcohol and squeeze the tip. In order to get rid of any buildup or dirt, you will lastly gently sweep the cotton swab around your circuit board. As you clean, swap out your cotton swab with alcohol as necessary.
- Dry: After clearing your circuit board of any dirt, leave it outside to air dry for about an hour before reinstalling it in your CPU.
Are fobs repairable?
While you might be able to repair a damaged fob, there are instances when it is just simpler to replace it. A replacement fob can cost as little as $50 depending on the make and model of your car, yet they may cost more in other instances and end up costing you quite a bit.
How does washing my key fob affect it?
There are many ways to accidently get your key fob wet, including dropping it in the pool, dropping it into a puddle, or leaving it in the washer. However, your key fob’s days are still far from over. You might be able to save your key fob from its watery encounter by using the following advice.
When you find your key fob is damp, you should have it dried out as quickly as you can. Your fob is less likely to survive its close call with death the longer you wait. This is due to the fact that your key fob may experience one or more serious issues as soon as it comes into contact with water:
- Voltage spikes – Because water is such a good conductor, it could quickly short out a portion of the circuit board in the key fob.
- Rust and corrosion will take their toll on the metal traces and other components of a wet circuit board.
- Failure of the key fob battery due to a moist circuit board is another possibility. The best case scenario is a dead battery. At worst, the battery can rupture or leak.
Focus on removing as much water as you can from your key fob before opening it after you’ve fished it out of whatever puddle, pool, or washing machine you happened to be in. First, turn the fob button side down and allow as much water to drain out as you can. Shake out as much water as you can, and then use a fresh cloth to polish the fob dry.
Then, set the fob button side down and give it some time to drain. In addition to catching the water, the cloth should also draw a little amount from any crevices that come into direct touch with it.
There may still be a little quantity of water trapped inside the key fob despite all of this effort. The key fob should now be carefully opened. Small Phillips, Torx, or Allen-head screws hold some fobs together, whereas flat screwdrivers are required to delicately pry apart others.
Once the key fob has been opened, carefully dry out the circuit board and the interior of the case as much as you can. To eliminate any remaining contaminants, carefully wipe the circuit board with a cotton swab dipped in 90 percent isopropyl alcohol, and then let it to dry entirely.
Additionally, verify sure the battery isn’t leaking by carefully inspecting it. If it is, carefully take out the battery and use a cotton swab dipped in distilled white vinegar to rub the trouble spots. By doing this, the acid will be neutralized and cleanup will be safer.
In case the battery was harmed or completely used up after the accidental submerging, it is a good idea to replace it as a preventative measure. Before inserting the new battery, clean the contacts on the circuit board with isopropyl alcohol after removing the old one.
Reassemble the key fob carefully and test it after making sure it is completely dry. If it functions, you are ready to go. You might need to disassemble the key fob and thoroughly clean the impacted contacts once more if just some of the buttons function. Check to see whether the key fob needs to be reprogrammed after being out of action if it doesn’t work at all.
Despite completing all of the aforementioned instructions, your key fob may still not function. Therefore, if your key fob breaks, don’t be upset; instead, consider it a lesson learned. Even though you’ll lose a few hundred bucks or more, at least you’ll be well prepared should the same issue arise again.
