I just tried the lock kit. The hitch pin that holds the receiver on to my vehicle is not long enough for my 2008 Sequoia or my 2013 tundra. What are the options on this? 581189


Comments
The Toyota OEM trailer hitch uses thicker walled tubing for the hitch receiver which prevents this hitch lock from working. The # RH5-XL
Trailer Hitch Receiver Lock - Extra Long - Flush Design for 2-1/2" Trailer Hitches
$26.58
is long enough to accommodate the extra width, and would work well.

Lock kit came quickly even with economy shipping. Seam like very good quality. I like the fact everything is keyed alike makes using it less of a chore. This was my second order, have been impressed with products and service. 560792

They are easy to use, especially since they are all keyed alike. I added wheel X-chocks with locks between my tandem axle wheels for added security. I don't know if all these locks have discouraged anyone from trying to steal our trailer, but it can't hurt to make it look as difficult and inconvenient as possible. Plus, you try to park in open, high visible areas when possible. They do help my peace of mind when I have to leave my trailer for any time. 525631


Comments
Still using them. I saw where someone tried to pry the hitch lock with a crowbar. It doesnt look like they tried very hard. Maybe something scared them off or maybe they noticed the wheel chocks and quit trying, I dont know. The main thing is they didnt get our trailer! The more locks, the better!

Have had this lock for a year now. All 3 pieces are working just fine. Even the rubber cover over the keyhole is still there and fits like a glove, usually the strap breaks and the cover gets lost. Not on this bad boy! Have used this on 2 different trailers, sure is nice having one key. 458936

Latch pin and receiver pin lock are top quality items. 3 stars because the tongue cover slides right off of my trailer so it is a useless item for my trailer! 458850



- C23088
by:

The trailer hitch lock did not fit my Airstream trailer hitch so it was useless although the other two fit the only one I have even a little confidence about is the one that holds the ball portion of the hitch to the vehicle. The other that keeps the ball attached to the trailer is only good for that purpose as it could be broken easily and removed so for security purposes almost useless. 458651

Nice to have a single key for everything. Coupler locks work great. The receiver lock is too short for my 2008 Toyota Sequoia hitch, so I can't use it. Make sure you measure all your hitch pieces before ordering. Quality feels good. 369186

Ask the Experts about this Curt Trailer Coupler Locks

  • Can Keys for Curt Trailer Locks be Duplicated
    A locksmith could duplicate the keys used for Curt trailer hitch locks # C23088. Since your business uses cargo trailers you might also be interested in tracking devices such as the Linxup GPS Vehicle Tracking Device # 300-AT3-S. So if a trailer is ever stolen you will be able to find it and bring the thieves to justice! I have linked a video for you.

  • Recommended Locks for Trailer That Are Keyed Alike
    To get multiples of all of those parts keyed alike is not an option. To get them keyed alike for one trailer/truck however is an option. I recommend the Curt Trailer Hitch Receiver and Coupler Lock Set - 2" Hitches - 2" or 2-5/16" Ball # C23088 for that application. Multiples of this part number will each be keyed differently.

  • Will The Curt Trailer Hitch Receiver and Coupler Lock Set Fit A 2009 Toyota Tundra Hitch?
    Yes. The Curt Trailer Hitch Receiver and Coupler Lock Set, # C23088, will fit your 2009 Toyota Tundra with 2 inch trailer hitch receiver. You will not need an extra long lock. I've attached some videos for you of this lock and it's function. The coupler lock will secure your trailer when unconnected, the coupler latch lock will secure your trailer when connected, and the hitch lock will secure your ball mount to your hitch. These three locks are key-alike and this kit comes with two...

  • Coupler Lock and Trailer Hitch Receiver Lock That are Keyed Alike
    There is a combination coupler lock and hitch receiver lock which can be keyed alike though the Atwood AT89017 and AT89011 cannot. Instead, you can use the Curt Trailer Hitch Receiver and Coupler Lock Set - 2" Hitches - 2" or 2-5/16" Ball # C23088. I've added links to a pair of video reviews of these locks for you to take a look at.

  • Compatibility of Curt C22321 Anti-Rattle Device w/ Curt C23088 Receiver and Trailer Coupler Lock Kit
    I'd recommend using a different anti-rattle solution like # RM-061, which would be compatible with the lock kit.The # C22321 Curt Anti-Rattle pin wouldn't work in conjunction with the Curt # C23088 lock set that you'd mentioned, becasue the # C222321 is actually a threaded hitch pin. If that were used, you couldn't use the hitch lock inlcuded in the lock kit. I've linked you to a video showing how the # RM-061 anti-rattle device works.

  • Recommended Trailer Coupler Locks Keyed Alike for Multiple Trailers
    The Master Lock Trailer Hitch Receiver Lock and Coupler Lock Set - 1-1/4" and 2" Hitches # 3794DAT does not allow for a keyed alike option at all. For a keyed alike option, I recommend the Fastway Universal Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Couplers # DT25013KA if you just need the coupler locks. To order multiples, select keyed alike and then adjust the quantity before adding to cart. If you need coupler and trigger locks keyed alike then I recommend the Curt Trailer...

  • Recommended Weight Distribution and Anti-Sway System For 2004 Range Rover And 7500 GVWR
    For a weight distribution system with anti-sway, you want to look at the total tongue weight of you vehicle and trailer. The total tongue weight is the loaded tongue weight of your trailer combined with any cargo weight behind the rear axle of your towing vehicle. For your 2004 Range Rover, that would be your cargo area when loaded. Your trailer tongue weight when loaded is normally between 10 and 15% of your total trailer weight. With this in mind and considering for some cargo...
