It seems Toyota Tundra engineers went a little bonkers with respect to self-programming of factory keyless entry remotes a decade ago. Toyota used keyfobs with FCC ID GQ43VT20T on many vehicles from as early as 2004 to as late as 2017. This family of remote transmitters was used on Avalon and Solara sedans, Sienna vans, Highlander and Sequoia SUVs and Tacoma and Tundra trucks. In short, they appear on a lot of vehicles. See the many GQ43VT20T remote button configurations at the following link: Toyota Remotes with FCC ID GQ43VT20T
For many vehicle model years, these parts are user-programmable, meaning that an owner can program the vehicle him or herself to add a new remote transmitter. Up until the 2008 model year, every vehicle that used this part was user programmable. Then, for some unknown reason, Toyota changed something so that 2008 Tundras require a special computer “scan” tool for programming. The following year, Toyota switched back so that 2009 Tundra trucks were again user programmable. And then, in 2010, they switched back for good to requiring scan tool programming. This kind of flip-flopping is very unusual in the auto industry, though not unprecedented.
Maybe Toyota engineers just want to keep us all on our toes?!
We recently received an inquiry from a woman looking for a replacement remote for an older Cool Start (CrimeStopper) system that originally used transmitter part number CS-409TX. That remote is no longer made. But there are newer remotes made by CrimeStopper that replace discontinued key fobs from many older systems.
The CS-409TX remote can be replaced by our part number 071-6497. The price is $49.00. Programming instructions and free phone technical support are included with purchase. You can see both parts and purchase 071-6497 at the following link to our website:

A customer contacted Remotes Unlimited to ask about a replacement for his 4-button Prestige alarm system transmitter with FCC ID ELVATCB. This remote – our part number 656-1656 – is no longer made. We no longer have any new 656-1656 parts in stock. However, we do have both B-grade (used) 656-1656 parts in stock and also factory new remotes of part 263-1263, which is a compatible Prestige part with FCC ID ELVAT0H and a slightly different button configuration.
Both of these parts can be seen at the following link:

Directed Electronics, DEI, has sold many add-on remote start systems that use 1-button keyfob transmitters. These systems have been sold under the brands AutoMate, Avital, Clifford, Python, Ready Remote, and Viper. The most common FCC IDs on these remotes are EZSDEI471H, EZSDEI7113 and EZSDEI7116. Many of these key fobs are no longer made, but Remotes Unlimited has many of them in stock either as a new remote or as a B-Grade remote. B-Grade remotes are used remotes that have been cleaned, tested and given a new battery.
Beginning around 2007, Ford started moving from use of stand-alone keys and remote fobs to use of an integrated part with the remote transmitter functions in the key head. In doing so, they did not change the transmitter technology for many years thereafter. So, stand-alone remotes can be used to replace the transmitter functions of a Ford keyhead part through 2014 or so.
In addition to the keyless entry transmitter technology, an integrated keyhead part has a transponder in it that interacts with the anti-theft system in the steering column. To use either a new integrated keyhead part or a stand-alone remote with one of these Ford vehicles, systems in the vehicle have to be programmed to accept the new part.
Programming a vehicle oneself to accept the anti-theft transponder in a new keyhead part involves a procedure that requires two distinct keys that already work for the vehicle. This programming procedure also supports programming of the transmitter functions.
If one is adding a stand-alone key fob remote only, a second procedure that only requires one key can be used.
Recently, Remotes Unlimited received an email from a website visitor who wanted to replace his “lost Alpine car alarm fob B30611753 used on 2004 Subaru Forester”. We suspected that B30611753 was a serial number, not a part number. Here is our response to the customer:
Alpine made early keyless entry systems that were used on Subaru Foresters and other models. The most common Alpine remote used by Subaru is our part 112-1112, a 2-button remote with FCC ID A269ZUA111. You can see it at the following link:
Subaru remote with FCC ID A269ZUA111
You can see from our website that Subaru has discontinued production of part 112-1112 and replaced it with a newer “teardrop” style remote, which is our part number 621-1621. We have both B-grade (gently used) 112-1112 remotes and new 621-1621 transmitters available.
Audiovox, Code Alarm and DEI (Directed Electronics) sell remote start systems under numerous brands, including Automate, Avital, Clifford, Prestige, Pursuit, Python and Viper. Automobile dealers and also tint/alarm shops install these systems. Many blog readers comment or call us to find out where they can get replacement remotes for these systems. Remotes Unlimited offers a broad assortment of replacement keyfobs for remote start systems.
One of the most common remotes is DEI part 7111A/7111L/7111P/7111V, a 1-button remote with FCC ID EZSDEI471H. The logo varies depending on whether the system is branded Automate, Avital, Python or Viper, but the circuit board inside is the same for all of these parts. Some versions are no longer made by DEI, but Remotes Unlimited has a good inventory of these parts. See an example of the Automate remote at the following link:
Automate part 7111A – 1-button remote with FCC ID EZSDEI471H
Another common remote is the tiny 1-button Code Alarm remote with FCC ID GOH-PCMINI. This remote was used on dealer-installed remote start systems with numerous brands on the remote. See samples of this remote at the following link:

Remotes Unlimited has these transmitters on sale for $39 each right now. (In many cases, we have gently-used B-grade keyfobs available for $24.) The systems that use these remotes are user programmable for adding a new remote. Programming instructions and free phone technical support are included with purchase.
