Utilizing DSC’s unique wireless technology and the latest production techniques, the WS4939 incorporates new features and benefits into a sleek design that is compact and user-friendly.

The WS4939 four button remote wireless key fob has four programmable buttons and offers three optional rubber key configurations to cover most applications. The built in LED tells you when a transmission has been sent and with feature controls such as arm and disarm, panic, and garage door controls, the fob provides versatility and reliability. The WS4939 can be used to arm/disarm security systems from a distance, be programmed to trigger garage door openers, turn on lights, open powered gates, or trigger panic alarms. A multi-function clip allows the wireless key to be clipped to a convenient location, whether it’s on a belt or car visor. The WS4939 wireless key is built with reliable 433 MHz technology, uses long-life lithium batteries and is compatible with all current DSC wireless receivers. The WS4939 is compatible with the following receivers: MAXSYS Wireless Receiver PC4164-433 PowerSeries Wireless Receivers PC5132-433 and RF5108-433 Fixed-Message LCD Keypad with Integrated Wireless Receiver RF5501-433 Envoy LCD Self-Contained Wireless Security System NT9005 Review: Works just like expected from description - Rather than trusting online help of a unnamed security supplier which lead me to order the wrong key fob for my DSC PC5010 system with RF5123 wireless receiver installed, I found the correct reference to ensure this WS4939 fob would really work. So going through the simple steps *8 804 41 # # did the job. The aspects to be certain about are 1. it works at the RF frequency of your receiver 2. it uses the required ESN number size (in this case 6 digits not 8 that I got misled by incompetent online help) 3. compatibility with your security system design. I needed no such thing as programming the keys since they were already preset in my case to the needed functions depicted on the buttons. Review: Fantastic replacement! - Exactly what I needed! Great replacement. ## Features - 4 programmable function keys - Small compact design - Full 3 second delay on panic key to reduce false alarms - 433 MHz technology - Belt clip included ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000TK79WS | | Best Sellers Rank | #773,352 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #2,511 in Garage Door Keypads & Remotes | | Brand Name | DSC | | Button Quantity | 4 | | Color | Black, Blue | | Compatible with Vehicle Type | Car | | Customer Reviews | 4.4 4.4 out of 5 stars (493) | | Manufacturer | DSC | | Material Type | Plastic | | UPC | 712324480573 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** DSC - **Color:** Black, Blue - **Material:** Plastic - **Number of Buttons:** 4 - **Vehicle Service Type:** Car ## Images ![DSC WS4939 Wireless Key Fob - Image 1](https://m.media-amazon.com/images/I/61GT9LgW6CL.jpg) ## Questions & Answers **Q: ADT wouldn't tell me how to sync with my system; does anyone know where I can find instructions on how to do this?** A: Go to dsc website. You will need to have the installers code. He should have either given you the 4 digit code or changed it to your choice. On the keypad hit *8 code then 804 then follow the fob's instructions **Q: Can anyone suggest how to prevent buttons from being pushed while the fob is in my pocket? I keep tripping the panic alarm by just sitting or leaning.** A: Happens to me all the time with my GMC truck remote. I just put a piece of clear scotch tape over the button and it stops accidental pushes. You'll still be able to push the button if you ever need to. **Q: How long do the fobs last** A: Actually they last a long time but what does break is the plastic loop that holds the fob onto your keychain. The two that I've replaced have been because of a broken loop. **Q: How to replace the battery?** A: I'm sure you can but I've never had to replace one yet. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works just like expected from description *by J***M on February 11, 2024* Rather than trusting online help of a unnamed security supplier which lead me to order the wrong key fob for my DSC PC5010 system with RF5123 wireless receiver installed, I found the correct reference to ensure this WS4939 fob would really work.

Great replacement. ### ⭐⭐⭐⭐⭐ It Works! *by J***N on October 3, 2023* I read other reviews and so I tried the last four digits of my ADT account, but it didn't work. I watched some videos and found out that they often use 6321 as the installers code, and it worked! All of the other instructions were good. ## Frequently Bought Together - DSC WS4939 Wireless Key Fob - DSC WS4939 Wireless Remote --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/3544234-dsc-ws4939-wireless-key-fob](https://www.desertcart.gr/products/3544234-dsc-ws4939-wireless-key-fob) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-16*
