Stoplock: understand the range before choosing
Stoplock is a vehicle-security brand distributed by Saxon Brands. The present AutoMotoPart range contains four visibly different steering-wheel locks—Original, Airbag, Professional and Pro Elite—plus one signal-blocking pouch. A lock is an additional physical deterrent, not proof that a vehicle cannot be stolen; the correct model must fit the exact wheel without contacting airbag, horn, switches, display or control stalks.
AutoMotoPart currently lists 5 Stoplock items. The largest Stoplock groups are 4 steering-wheel-lock entries and 1 signal-blocking-pouch entry. Stoplock totals can change, so a category count is orientation rather than proof that a particular reference suits a vehicle, workplace or job. The exact Stoplock listing, its current technical information and the item in front of you must agree.
What the Stoplock page actually covers
| Product group in this range | Current entries | Selection focus |
|---|---|---|
| Steering-wheel locks and signal-blocking pouch | 5 | Match the exact vehicle, year, wheel, airbag boss and control clearance in the current application guide; use the pouch only after a live signal test. |
Four entries immobilise a steering wheel mechanically; the fifth is a soft signal-blocking pouch. Original, Airbag, Professional and Pro Elite are model names, not quality grades that can be substituted without checking. The pouch neither replaces a steering lock nor shares its fitment method.
Build a reliable shortlist
Start with the threat and the vehicle. Record make, model, year, steering-wheel option and any wheel change from standard. Inspect the wheel and airbag area in daylight, then use the latest Stoplock guide. For a keyless vehicle, identify every active and spare fob and the handbook's keyless settings.
| Check | Why it matters | Useful evidence |
|---|---|---|
| Guide result | Stoplock says airbag size means not every variant fits every wheel | Current application guide for exact model and year |
| Wheel geometry | Diameter alone omits rim thickness, spokes, boss and airbag profile | Actual wheel inspection and trial without force |
| Controls | A bar or fork can press horn, switches, paddles, stalks or screens | Full clearance in the final locked position |
| Occupant safety | A heavy bar fitted or stored badly can injure or obstruct | Remove-before-drive routine and secure storage location |
| Pouch test | Signal attenuation depends on full enclosure, closure and condition | Vehicle unlock/start test with main and spare fobs |
| Layering | One device addresses only part of the theft route | Vehicle locking, keys, alarm/immobiliser and other appropriate measures |
Reject any lock that needs bending, hammering, pressure on the airbag cover or a position that compromises controls. If a vehicle is absent from the guide, has an aftermarket wheel or the guide result conflicts with the actual wheel, ask Stoplock/Saxon Brands for a current recommendation before use.
Original, Airbag, Professional and Pro Elite
Saxon Brands lists Original as HG 134-59, Airbag as HG 134-66, Professional as HG 149-00 and Pro Elite as HG 150-00. Retain these references when checking a guide or requesting replacement keys. Similar yellow-bar appearance does not show the fork arrangement, curvature or working clearance that decides fit.
Original is the compact snap-shut design in the official range. Airbag is formed for larger vehicles and large airbag bosses. Professional is a separate attack-tested design, while Pro Elite combines twin locking forks with a deeper bend and is described by the distributor as having the broadest fit among its sister models. Broad fit remains conditional on the application guide and physical check.
Airbag and steering-control boundaries
The centre pad can contain an airbag module whose cover must remain unobstructed and undamaged. Do not rest a fork or bar against the cover, wedge anything into its seam or use the lock as a lever on the wheel. Never alter the wheel, airbag, lock or its protective coating to create space. A warning lamp, damaged cover or prior airbag deployment needs vehicle-specific repair, not a different lock position.
Check the horn with the lock removed and note whether the proposed position would hold it on. Preserve access and clearance around multifunction buttons, heating controls, gear paddles and column stalks. A lock should not touch a digital instrument panel or centre display. If it can rotate after locking and strike one of these parts, the fit is not acceptable even when the key mechanism closes.
A safe fit-and-remove routine
Park fully, select the appropriate gear or parking position, apply the parking brake and switch off according to the handbook. Keep the Stoplock key separate from the vehicle's enclosed keyless fob. Place the forks only at the locations supported by the current instructions, close without excessive force and tug-check the device while avoiding stress on the wheel.
Before entering to drive, unlock and lift the complete device clear. Check that no sleeve, fork or bar remains around the rim, then place it in a secured boot or purpose-designed restraint where it cannot reach pedals or occupants. Do not put it loose on a seat, parcel shelf or footwell. Confirm normal steering and warning-lamp status before moving away.
Using and testing the RFID pouch
The current Saxon Brands Stoplock pouch is SKU SS5433 with a secure fastening and keyring hook. Its official page calls it a universal-size product and also describes phone storage, but physical size and claimed signal blocking are separate questions. Place the fob in the shielded compartment rather than an unlined outer pocket and close the fastening across its full width.
With the pouch closed, stand at the normal unlock point and try passive entry; where safe and allowed by the handbook, verify that the vehicle cannot detect the key for starting. Test main and spare keys separately and repeat every few months or after damage, as current police advice recommends. If the vehicle responds, reposition and close once; if it still responds, replace or stop relying on the pouch.
Understand what each layer cannot do
A steering lock provides a visible and physical obstruction, but it cannot prevent every attack on the wheel, lock, glass, diagnostic port or key system. A pouch targets the communication path used in a relay attack; it does not prevent someone using the genuine key after burglary or theft, and it does not disable credentials already copied or programmed.
Lock the vehicle and check that it actually locked, keep all keys away from doors and windows, and use manufacturer settings such as disabling passive entry where appropriate. Keep key codes and replacements controlled. Do not leave a Stoplock key with the vehicle key inside the same unprotected location. Security improves when independent layers are used correctly rather than when one device is described as absolute protection.
From identification to a checked result
| Stage | Good practice for this range | Mistake to avoid |
|---|---|---|
| Identify | Record vehicle/year, wheel option, Stoplock reference and every fob | Assuming a model labelled Airbag or Elite fits universally |
| Trial | Check guide result, fork engagement and all airbag/control clearances | Forcing closure or accepting movement into controls |
| Secure | Fit only after parking and tug-check without loading the wheel | Fitting while manoeuvring or leaving the vehicle unsecured |
| Remove/store | Take off completely before start and restrain the heavy lock | Driving with it fitted or leaving it in a footwell |
| Test pouch | Fully enclose each fob and repeat vehicle detection tests regularly | Assuming a closed-looking or worn pouch still blocks signals |
Keep the lock reference and key code separately and securely, without publishing them or attaching them to the vehicle key. Add a recurring pouch test and lock-condition check to the security routine. Replace a damaged coating, bent fork, unreliable cylinder or failing pouch rather than improvising a repair.
Reading real Stoplock references
The Stoplock names below are examples from the current range and show why the complete description matters. They are not universal Stoplock recommendations and should not be treated as a fitment list. Within Stoplock, a shared family word can conceal a different dimension, connector, material, pack format, operating condition or installation side.
| Example listing | What to verify beyond the name |
|---|---|
| Steering Wheel Lock - Original | Original/HG 134-59, current guide result, wheel and airbag/control clearance |
| Steering Wheel Lock - Airbag | Airbag/HG 134-66, large-boss geometry, secure engagement without cover pressure |
| Steering Wheel Lock - Professional | Professional/HG 149-00, exact guide fit, twin-point clearance and secure storage |
| Steering Wheel Lock - Pro Elite | Pro Elite/HG 150-00, deeper bend/twin forks, actual wheel trial without rotation |
| Anti Theft RFID Protection Pouch | SS5433 pouch, shielded compartment, full closure, main/spare fob detection test |
The lock names describe distinct constructions; they do not form a simple smallest-to-largest ladder for every vehicle. Use the application guide first and the real wheel as the final fit check. Treat the pouch as a tested radio-signal layer, never as a fitment accessory.
Common errors around Stoplock products
- Calling any Stoplock model universal without consulting the current application guide.
- Allowing a fork or bar to press the airbag cover, horn or wheel controls.
- Forcing the lock shut, altering a fork or accepting a loose rotating fit.
- Starting, manoeuvring, towing or driving while the steering lock remains fitted.
- Leaving the heavy device loose where it can reach pedals or occupants.
- Putting a fob in an unshielded pocket or failing to close the pouch fully.
- Testing only the main key while a spare remains exposed near the vehicle.
- Treating RFID shielding as protection against every theft or radio technology.
Stoplock questions and answers
Q: Which Stoplock products are listed here?
A: Original, Airbag, Professional and Pro Elite steering-wheel locks plus the SS5433 signal-blocking pouch.
Q: Will any Stoplock fit any car?
A: No. Stoplock's guide says airbag size and wheel design mean not every variant fits every vehicle.
Q: Is Airbag automatically right for an airbag wheel?
A: No. It is shaped for larger airbags, but the exact vehicle/year guide and real-wheel clearance still decide.
Q: What is different about Pro Elite?
A: Saxon Brands describes twin locking forks and a deeper bend for larger bossed wheels and broader tolerance.
Q: Can the bar touch the airbag cover?
A: No. Reject a position that presses, wedges or could damage the airbag cover or its seams.
Q: Can it rest against horn or wheel switches?
A: No. It must lock without activating or loading controls, paddles, stalks, trim or displays.
Q: May the vehicle be moved with the lock fitted?
A: No. Remove it completely before starting, manoeuvring, towing or driving.
Q: Where should the removed lock be kept?
A: Secure it so its weight cannot make it a projectile or let it obstruct the pedals.
Q: How should the pouch be tested?
A: Fully close it around the fob and confirm the nearby vehicle cannot unlock or recognise that key.
Q: Does one successful pouch test last forever?
A: No. Repeat regularly and after wear, folding or fastening damage.
Q: Does the pouch stop every form of keyless theft?
A: No. It addresses signal relay when effective; stolen keys, programming, forced entry and other routes need other controls.
Q: Should spare keys also be shielded?
A: Yes. Police guidance recommends protecting and testing spare fobs as well as the main one.
