Best Antitheft Keyless Entry Systems of 2025

"I found this remote to be excellent! It worked perfectly for my 2004 Dodge Ram, and now I enjoy the remote start feature. It's a fantastic upgrade for my older truck!"

"After installing this security system in my 2014 Mustang, I had to get creative with wiring. It took about four hours to install, but now the alarm is loud enough to get attention, especially in my well-lit apartment complex."

"I wanted a simple alarm that could control my door locks and trunk. After purchasing a wiring diagram, I found the connections straightforward. The siren was weak, so I connected it to my horn, and now everything works great!"

"I found the installation to be very easy since I'm familiar with automotive wiring. Just a tip: leave the (key on power) wire disconnected unless you want the doors to lock every time you turn on the ignition. I installed two of these units in my 1987 Cougars without any issues."

"The assembly process was nearly impossible for me, and even after putting it together, it didn’t work properly."

"The wiring instructions could use some improvement. Overall, it was fairly easy to install, although one wire wasn’t labeled. I figured out it was for the auto lock feature when turning the key. I'm a bit concerned about the security since it’s a low-cost remote, so I wonder who else could unlock my car."

"I found it extremely easy to program my 2001 GMC Yukon. It took me literally 5 minutes to program both remotes, and everything I needed was included, not just a shell."

"These key fobs were a lifesaver! I had tried a local auto parts store, but their FOB didn’t work. I spent $62 on a faulty one before getting these, and they worked perfectly the first time!"

"I really appreciated that these keys were still available and they synchronized perfectly with my vehicle. It’s a great product for the price!"

"I found this alarm easy to install. At 20 years old, it was my first alarm installation, and with some wiring experience, it was straightforward. I put it in my 1996 Honda Civic Ex, and it took me and a friend about a day. The guide helped with the wiring, and aside from the not-so-sensitive sensor, it works great for the price!"

"After months of research, I finally purchased this Viper Alarm, and it arrived the next day. I replaced my old alarm with this newer model, and everything functions perfectly. The installation was easy, especially with a wiring diagram for my DC2 Integra. If I ever need another alarm, I would definitely buy this again!"

"I've had this alarm for five years, and honestly, it’s been quite a disappointment. Initially, it was sensitive to noise, but during two break-ins, no one heard it go off, despite it being loud. I don't know if it was the installation or the alarm itself, but it failed when I needed it most."

"I have a grade model Tundra, which means it's basic without any extra features. Tired of using the key, I checked with my dealership, and they quoted me $500 for keyless entry installation. Being a DIY enthusiast, I found this system after watching a few YouTube videos. I can honestly say it's really easy to install, and it works very well. I'm shocked at how inexpensive this is. If you're comfortable with wiring, I highly recommend it!"

"I’ve installed probably a dozen keyless entry systems, and while they don’t vary much, I chose this one for its low-profile fob. It's slim and lightweight, perfect for my keychain. I’m planning to buy another one for my other vehicle. The fobs alone are worth the $20, and the LED indicator that shows when the unit is locked is a nice touch."

"Initially, I was thrilled with this keyless entry system. It was super easy to hook up, and the remotes felt high-quality. However, just two days later, it stopped working completely. I’ve installed many systems before, so I’m confident it’s a unit failure. I was hoping to replace my old system, but I guess I’ll have to invest in a more recognized brand this time."

"I found the installation to be straightforward and quick. I tackled it myself after checking some online resources. Now, I can unlock my truck without fumbling for keys, which is a huge convenience!"

"I've installed multiple units before, and I appreciate the durability of this one. However, the instructions can be a bit vague, especially for those who aren't familiar with wiring. But once installed, it works perfectly!"

"I recently put this in my 2003 F250 after watching a helpful YouTube video. The process was easy to follow, and now I enjoy the benefits of keyless entry without any hassle!"

"I bought this for my older cars that had power door locks but lacked keyless entry. Installation was straightforward, though the wiring diagrams were a bit confusing. I had to look up some additional info online, but it’s nice to have keyless entry now!"

"This was a great purchase for my project car. I had issues with the key getting stuck, and this upgrade solved everything. The installation did require some wire splicing, but overall it was pretty simple."

"I found this remote door lock kit to be a low-cost solution. I needed to do some research to identify the locks in my 1994 Ford Taurus, but once I installed it, it worked perfectly. No more fumbling for keys!"

"I found this product to be great for adding keyless entry. The installation was a bit of a challenge since I had to wire things up correctly, but once I did, it worked perfectly. The range is impressive, and I appreciate the clean design of the fobs."

"After a few days of tinkering, I managed to install this system in my Dodge. I had to get some resistors, but everything else went smoothly. I opted not to wire the horn or lights, but I love that the flashing light indicates when the doors are locked. Overall, a solid product."

"I previously installed a different brand in my Mustang and was excited to try this one. The compatibility with my old setup was a pleasant surprise, and I was able to upgrade easily. The installation instructions were a bit lacking, but I figured it out as I went along. The only downside is that the trunk feature doesn't work for my car, but the essential functions are great!"

"I found it easy to install on my 1992 F-150. While the horn constantly blasts instead of a quick chirp, and the first parking light flash is a bit weak, it does its main job of locking and unlocking the doors. For the price, I consider it acceptable."

"Unfortunately, after about 10 days, the lock and unlock feature failed. If I had spent more, I would be frustrated, but given the cost, I’m not overly upset. I’ve learned my lesson and will likely buy the more expensive system I initially considered."

"This device works perfectly for me. The instructions were sufficient, just remember you can configure it as a 12v trigger or ground trigger. The key blanks could use an update, but overall, it functions well."

"I installed this in my 2018 Toyota Corolla L, which surprisingly didn’t come with a remote feature. The installation wasn’t too hard, and it works at a great distance. I really like this product."

"After about 6 months, both keys are still working. Programming them to the unit was a bit tricky, and I recommend having a second person to help. If you can wire an outlet, you can probably install this, but the included instructions are not very helpful."
